Folger Pinnacle Maintenance Mission Complete

nnk@uvic.ca — Fri, 25 Oct 2013 07:00:00 +0000

On Wednesday, 23 October 2013, Folger Pinnacle platform received its last maintenance and clean-up service for the year; the right in time before the November storms will be surging across the coast again. The experienced divers from Pelagic Technologies and the Bamfield Marine Sciences Centre swapped the Folger ReefCam (also known as Outreach camera) for an overhauled and nicely cleaned one, installed several test instruments (development of the Ocean Networks Canada Innovation team) and, finally, thoroughly cleaned all instruments hosted on the Folger Platform.

Stunning improvements in the data quality were observed in the 3D Camera Array (see picture), and also the current-meters provide now more accurate data. Hopefully the colder seas, shorter days, and the upcoming storm season will prevent exorbitant growth on the instruments over the winter month until save diving is possiible next year.

Many thanks to Pelagic Technologies and the Bamfield Marine Sciences Centre for their help with this mission!

Introduction to Folger Passage

Folger Passage at a Glance:

Region: Southwest coast of Vancouver Island, a short sail west of Bamfield, B.C in the mouth of Barkley Sound
Instrument Platforms: Folger Pinnacle and Folger Deep
Depths:
- Folger Pinnacle: 23 m
- Folger Deep: 100 m
Locations:
- Folger Pinnacle: Lat: 48.80829 N, Lon: -125.2815 W
- Folger Deep: Lat: 48.81378 N, Lon: -125.28095 W
Seafloor Composition: Diverse, from sandy sediments and gravel near Folger Deep to cobbles, boulders, and rocky pillars at Folger Pinnacle.
Principal Research: WCVI Marine Ecosystem Project. ocean biogeochemistry, terrestrial-marine interactions, coastal physical oceanography, phyto- and zooplankton, fish, and marine mammals.

Environment/Ecosystems:

Located where terrestrial and marine ecosystems collide, the Folger Passage ecosystem is particularly rich in both species density and diversity. One of the most intriguing aspects of the Folger Passage is the fact that two distinct, yet interconnected ecosystems are incorporated within it.

The first system, at Folger Pinnacle, is a near-shore reef ecosystem with abundant sponges, anemones, bryozoans, and seaweed making up the colourful backdrop for more motile families of organisms, such as molluscs, rockfish, and a myriad of echinoderms.

Characterized by mixing wave action and abundant light, the Folger Pinnacle ecosystem stands in stark contrast to that of Folger Deep, some 80 m below the pinnacle, which plays host to a dense zooplankton community feeding the abundant fish schooling in the water column above.

What Makes Folger Passage Unique?

Folger Passage is a unique laboratory in that it monitors a reef ecosystem driven by the physical oceanographic process of upwelling, whereby cold, nutrient-rich waters are drawn up from the deep by the offshore, wind-driven movement of warm, nutrient-poor surface waters.

Flushing the sunlit reef ecosystem of Folger Pinnacle with cold, nutrient- and oxygen-rich water from Folger Deep, placement of the Ocean Networks Canada’s Folger Passage node then allows the unique opportunity to monitor upwelling in action, and to better understand the process and ecosystem which are intimately linked to the health of Canada’s Fisheries.

Being ONC's shallowest installation site, Folger Pinnacle is indeed shallow enough for cameras to show images during daylight without the need for artificial lights whose usage, for marine protection, usually needs to be limited.

Principal Research:

The West Coast of Vancouver Island (WCVI) Marine Ecosystem Project, led by Scientist Ron Tanasichuk of Fisheries and Oceans Canada, aims to explore the impacts of oceanographic processes, such as currents, ocean mixing, and storms, on coastal marine life through the following studies:

Acoustic Current Visualization using Acoustic Doppler Current Profiler (ADCP) devices at both Folger Deep and Folger Pinnacle.
Scientist Rich Pawlowicz from the University of British Columbia is using acoustic data from BioSonics Echousounders to study fish, plankton and bubbles across Folger Passage.
LIDO (Listen to the Deep Ocean), led by Michel André, is a project that uses hydrophones from across NEPTUNE observatory to measure bioacoustics of deep sea environments. Hydrophones are also the key instruments used in the Fin Whale Vocalization study, led by William Wilcock from the University of Washington’s School of Oceanography.
A pilot project, led by Scientist Dilumie Abeysirigunawardena, takes an unconventional approach to storm watching by using data on temperature, oxygen and salinity fluxes to measure the impacts of storm-related deep water mixing on ecosystem dynamics.
A focused study by Sally Leys and Herb Yang on Sessile (non-motile) Suspension Feeders, such as mussels, or sponges, uses a custom-built 8-lens camera system to capture 3D images from the Folger Pinnacle Instrument Platform.

Folger Pinnacle Back Online

rlat@uvic.ca — Fri, 26 Oct 2012 07:00:00 +0000

Folger Pinnacle instrument platform, part of Ocean Networks Canada's Folger Passage site, is now back online, streaming data and video from 23 m below sea level in Folger Passage.

Instruments attached to this platform:

This instrument platform was reinstalled by divers last month but could not be reconnected to Folger Node because, at 100 m, it is too deep for diver operations. We originally planned to reconnect it during the autumn maintenance and installation cruise aboard the R/V Thompson, but when ship repairs delayed our cruise until next spring, we scrambled to find an alternative. Fortunately, it is now up and running, thanks to help from the crews of the Georgia Transporter and the CanPac Oceanic Explorer remotely operated vehicle (ROV).

The Georgia Transporter barge, with ROV onboard, arrived in Bamfield on 15 October, but bad weather delayed dive operations for 4 days. Seas were still somewhat rough on the day of installation, with 2.7 m swell measured that morning at La Perouse Bank to the west of Vancouver Island, but crew members were able to successfully launch the Oceanic Explorer. The ROV dove to the seafloor, retrieved the cable-end connector, and plugged it in to Science Port 2 on Folger Node. We were delighted to find that once connected, electrical and communications were established without a hitch.

One of the really interesting instruments on this platform is the Ocean Presence video cam, which provides a live video window to the fascinating and prolific reef habitat there. Dubbed "ReefCam", the video camera is now online and streaming live. The video can be viewed both via our ReefCam and the Oceans 2.0 camera page.

At a depth of 23 m, enough daylight filters down to Folger Pinnacle to clearly see fish, anemones, sea stars, barnacles, sponges and many other creatures inhabiting the reef. The camera system is also equipped with lights, which bring out the vivid colours of this rich environment. For our initial phase of use, we plan to turn the lights on daily, 8:00-8:45 AM and 12:00-12:45PM.

Many thanks to the crews of the CanPac Oceanic Explorer ROV (Dave, Tim, Cal) and the Georgia Transporter barge (Geoff, Todd, Ben, Nolan and John). Thanks also to Bamfield Marine Science Centre for their facility support.

Folger Pinnacle Re-installed

rlat@uvic.ca — Tue, 18 Sep 2012 07:00:00 +0000

Thanks to the help of three boat crews and a dive team, our Folger Pinnacle instrument platform is now reinstalled on a submerged reef in Folger Passage, ready to be reconnected to the network.

The platform, which was recovered earlier this year, has been cleaned, refurbished and upgraded with new instruments. The current instruments include:

upward-looking acoustic Doppler current profiler with wave option
downward-looking acoustic Doppler current profiler
single-point current meter
conductivity-temperature-depth instrument (new)
oxygen sensor (new)
light sensor
chlorophyll/turbidity sensor
video camera
3D imaging camera array

The installation took several days to complete and required teams and equipment from several different partner companies, including Pelagic Technologies, Ocean Dynamics Canada (ODC) and the Bamfield Marine Sciences Centre (BMSC).

First, the platform was transported via flatbed truck to Port Alberni, loaded onto the M/V Francis Barkley, and shipped to Bamfield Marine Science Centre, our base of operations for the installation project. NEPTUNE Canada's Jonathan Zand, Reece Hasanen and Alice Bui drove to Bamfield to prepare for the next day's installation.Then, on the second day, the crane barge Harbour Clearwater arrived to load the platform and associated deployment equipment. Part of our crew boarded the barge, while the dive crew set up shop aboard BMSC's M/V Barkley Star. Both vessels made their way to Folger Pinnacle, a short sail from Bamfield, and worked together to deploy the instrument platform.

The platform was lifted by crane over the side and into the water next to the barge. Then the divers attached large inflatable bags to the platform and filled them with air to provide floatation. Once it became neutrally buoyant, the platform was released from the crane and the dive crew dove with it, carefully guiding it down onto our platform frame on Folger Pinnacle (depth 25 m). The divers then bolted the platform onto the base frame and positioned the 3D Grasshopper camera array to focus on a particular yellow sponge, which will be the subject of intense scientific study over the coming months.

While this was going on, NEPTUNE Canada's Martin Scherwath and Justin Napier hauled the new electro-optical connecting cable from Victoria to Port Alberni. At Port Alberni, they were greeted by the Captain and crew of the M/V Crown Royal (operated by ODC), who helped spool the cable onto a drum mounted on that boat. The Crown Royal sailed to Bamfield via Alberni Inlet, while Martin and Justin drove the long and winding road to Bamfield.

The next day's task was to lay the cable from Folger Pinnacle instrument platform to Folger Passage node. For this work, ODC's M/V Crown Royal and their mini remotely operated vehicle (ROV), the Seaeye Falcon, were instrumental. First they lowered the cable end, with attached connection plug and termination canister, to the rocky pinnacle below. The dive team secured the cable with heavy chains. Then the cable was slowly spooled out as the Crown Royal navigated to Folger Passage node.

Folger Pinnacle reaches up into relatively shallow waters, accessible to professional divers. But Folger Passage node is installed 600 m away at a depth of 100 m—too deep for diving. This is where the Falcon ROV came in, deployed from the Crown Royal to inspect the cable lay in deeper waters. Finally, the node end of the cable, with its attached connection plug and termination canister, was carefully winched to the seafloor next to Folger Node.

The following day, the divers plugged in the cable end to Folger Pinnacle instrument platform and further work was done to secure and survey the cable. The disconnected end of the cable will rest on the seabed next to Folger Passage node until our next cruise, when a larger ROV such as ROPOS can be launched to plug it in, allowing power and communications to flow. The timing of this connection is not set as yet, but we hope to accomplish it as quickly as possible, so scientists can begin using the new instruments there.

Many thanks to Pelagic Technologies dive team (Glenn Hafey, Graham Starsage, Eric Hollett, Greg Watson, Steve Acciaroli), Ocean Dynamics Canada (Ralph North, Josh Chernov, Mike Dennis), Norwespac Industries (Jim Kyllonen, Josh Monufret), the Bamfield Marine Sciences Centre (Siobhan Gray, Dane Stable), Diversity Consulting (provided the Falcon ROV), Justin Napier, Alice Bui, Martin Scherwath and Jonathan Zand for their help with installation work. Thanks also to Jonathon Miller, Maia Hoeberechts, Mike Beard, Reece Hasanen, Ian Kulin, Kim Wallace, Clio Bonnett, Ryan Key and the Highland Technologies team for their tremendous help with platform preparation and integration.

Folger Pinnacle Frontiers

rlat@uvic.ca — Mon, 22 Aug 2011 07:00:00 +0000

The Folger Pinnacle instrument platform was installed on August 23, 2010 and connected on February 2, 2011 by a combined team of Pelagic Technologies divers, the Bamfield Marine Sciences Centre (BMSC), and Ocean Networks Canada. Since then, a wealth of data has been gathered by instruments affixed to this 23m deep platform. However, in recent months, Dilumie Abeysirigunawardena, one of our data specialists, noticed a drop in the instruments’ data quality and sensitivity. Some stopped working altogether, while signals from others have gradually diminished. (See, for example, the drop-off in irradiance from our light sensor below – you’d normally expect June to be brighter than February!)

Folger Pinnacle was not visited during our recent 3-week July cruise because it is the only site on the NEPTUNE Observatory that is serviced by professional divers; the other four nodes and the Folger Deep instrument platform (complement site at Folger Passage node; are too deep for divers and the waters at Folger Pinnacle are generally too turbulent for large remotely operated vehicles. In addition, Folger Pinnacle is a unique site, situated in a rockfish conservation zone, where sunlight penetrates to a shallow reef populated by an abundance of life.

Instrument Overview and Maintenance

We were warned by Captain John Richards of BMSC that our marker buoy was missing (again) so the first task when we arrived at location on August 2, 2011 was to install a new purpose-designed marker buoy.

On the seafloor, all the instruments desperately needed intensive cleaning due to extensive biofouling--in other words, barnacles, algae and other forms of life were taking over! This interferes with data collection as sensors and lenses become blocked.

There were 7 scientific instruments installed on Folger Pinnacle platform:

RDI Workhorse Monitor Acoustic Doppler Current Profiler (ADCP)
Nortek single-point acoustic current meter
Nortek Aquadopp ADCP
Biospherical Photosynthetically Active Radiometer (PAR) light sensor
WET Labs fluorometer and transmissometer
3D high-resolution camera imaging system and LED light array
Sidus HD video camera

We were pleased to have the expertise of Glenn Hafey and the Pelagic Technologies commercial dive crew again with us this summer. This is the dive team that previously helped us install and connect Folger Pinnacle. In addition, thanks to the BMSC scientific dive team led by Siobhan Gray who captured video footage of the operations and aided in cleaning the instruments.

When they first swam down to the platform, they thought it had disappeared. Every available surface had been colonized by reef creatures and some instruments were transformed beyond recognition.

Following specific instructions from manufacturers, divers restored some of the instruments with a multi-purpose scrub and wipe sponge, plastic spatulas, a small soft bristle brush, and cotton cleaning cloths. Zinc-oxide was smeared onto transducer surfaces to deter future biofouling, but we’re not taking any bets this won’t happen! Thanks to our intrepid dive crew, the instrument platform went through an incredible transformation and it became possible to distinguish the various instruments once again.

Camera Recovery

Two instruments did not remain with the platform. The divers retrieved the Sidus HD video camera and the 3D camera array. They also removed the bio shutter from our WET Labs fluorometer/transmissometer in a very delicate process (it apparently became stuck open when a barnacle took up residence between the copper plate and the optical surface).

The instrument recovery process with divers is much different than with ROPOS. In order to recover the 3D Camera Array and the Sidus Camera Assembly, divers had to unbolt them from the Folger Pinnacle instrument platform. Next, the divers attached lift bags to the cameras’ instrument frames and inflated them. The 3D Camera Frame weighs approximately 180 lb in water and 250 lbs in air, while the Sidus Assembly weighs approximately 19 lb in water and 30 lb in air. The bags were to make the instruments neutrally buoyant and easier to control. After that they attached a line to the camera frame, which was pulled up by the surface team led by Captain John Richards of BMSC using a capstan (a revolving vertical-axled type of pulley).

Results

After cleaning we were able to regain access to good scalar data from all instruments, including the single-point acoustic current meter, which had failed in June 2011.

The following data plots reflect the improvements seen after instrument cleaning.

1) RDI Workhorse Monitor ADCP

A clear improvement resulted for this instrument, as shown in the following two plots of beam 2 signal strength before (top figure) and after (bottom figure) the cleaning program. Average echo intensity increased from 77 counts (before cleaning) to 113 counts (after cleaning).

2) Nortek Current Meter

According to the data, beam 3 failed first. Notice that the diagnostic counts after cleaning program are well below the actual beam counts, which suggests good data. All three beams showed an increased sensitivity. Also note that the diagnostics counts (blue dots) are now well below the respective beam counts, providing sufficient gap to produces reliable current projections.

3) Nortek Aquadopp ADCP

The cleaning program improved the signal strength of all three beams on the Nortek Aquadopp profiler.

The Nortek downward-looking current profiler was performing satisfactorily even before cleaning; however, initial inspections showed significant biofouling. The dive team did some rigorous and delicate cleaning to remove bio-fouling from the transducers.

4) Biospherical PAR Irradiance

This device indicates the amount of ambient light detected at the platform (23m below the surface). Sensor sensitivity increased from almost nothing to very clear daily spikes beginning August 6, 2011.

5) WET Labs Fluorometer/Transmissometer

After the bio-shutter was removed and the instrument cleaned, the variability of chlorophyll captured jumped from zero to approximately 25 ug/l.

6) 3D high-resolution camera imaging system and LED light array

The 3D high-resolution camera imaging system is getting its lighting system repaired for redeployment in 2012. A research team led by Sally Leys and Herb Yang of the University of Alberta will use the custom-built 8-lens camera system to make 3D images of sessile (non-mobile) suspension feeders living beneath the platform.

7) Sidus HD Video Camera

The Sidus video camera was intended to provide a live video spyglass for researchers studying the rich ecosystem inhabiting Folger Pinnacle Reef. Unfortunately, the camera did not function properly, and will be replaced.

(More than) a Little Help from our Friends

All in all, the 3-day cruise was a great success! We are now implementing a regular cleaning and inspection program. We wish to thank both BMSC and Pelagic for their tremendous assistance with this important work!

Folger Pinnacle Connected

rlat@uvic.ca — Mon, 07 Feb 2011 08:00:00 +0000

Our Folger Pinnacle instrument platform is now up and running after a team of divers plugged in the extension cable connecting it to Folger Passage node and the rest of the NEPTUNE Observatory last week. Glenn Hafey of Pelagic Technologies made the actual connection after he and his 4-man team dove 23m to the platform from the Bamfield Marine Science Centre’s 9.8m aluminum dive support boat, the Barkley Star.

After the dive team was safely out of the water, we held our collective breath as our systems team powered up the platform and sent the first ping. Happily, the platform’s junction box responded! One by one, we then sparked up all 7 platform instruments:

RDI Acoustic Doppler Current Profiler (600kHz)
Nortek Aquadopp single-point acoustic current meter
Nortek Aquadopp Acoustic Doppler Current Profiler
3D Grasshopper high-resolution camera imaging system
Biospherical Photosynthetically Active Radiometer (PAR) light sensor
WETLabs fluorometer
Sidus HD video camera

All 7 instruments powered up successfully, however the HD video camera is not communicating with shore. Our science and technical team is trying to troubleshoot the camera communications, while working on commissioning the rest of the instruments. Some of our early commissioning data are now available via our Data Search and Plotting Utility tools.

23 August 2011: Initial Installation

After a lengthy period of fabrication, integration and testing, the Folger Pinnacle instrument platform, designed by Highland Technologies' Jason Williams, was finally ready for installation late in the summer of 2010. On August 23, it was installed on a sponge, barnacle and anemone-covered rock outcrop 23m below the surface. To prepare for installation, divers first drilled holes in the rock and glued rock bolts into them. Next, they attached the base platform to the rock bolts.

Once the base platform was ready, it was time to install the instrument platform. It was loaded by crane thanks to Lady Rose Marine and transported to the site on a small barge-like landing craft by Norwespac Ind Ltd., while the Bamfield Marine Science Centre (BMSC) M/V Alta supported the dive operations. The Pelagic Technologies dive team used inflated air bags to float the platform, then releasing some air, swam with it as it slowly sank. The divers carefully guided the platform downward and attached it to the base platform.

Installation Video

August 2010 – January 2011: Waiting Game

Unfortunately, the dive team was unable to connect the platform to our network last August, because the end of the extension cable was stuck in deeper waters, out of reach.

This cable was initially laid by ROPOS during the Fall 2009 installation cruise, before the platform was ready. The platform end of the cable had been secured to a fiberglass grating and left near the base of the Folger Pinnacle rock formation. We hoped it would stay there, but the cable end did not stay put. During the winter storm season, heavy surge and strong waves grabbed the grating and drug it down to nearby deep waters.

So, before we could connect the newly installed Folger Pinnacle platform to our network, we had to retrieve the cable end and carefully shift it to the platform—a painstaking task. It took three excursions, two boats and two Remotely Operated Vehicles (ROVs) to relocate the cable end and reposition it near the instrument platform. Ocean Networks Canada systems integration engineer Jonathan Zand oversaw these efforts, working with BMSC ship crews and ROV operators from International Underwater Surveyors (IUS) and SubOceanic Sciences.

In October, IUS used their Phantom ROV to remove slack from the cable line and reposition the cable end near the instrument platform. In November, SubOceanic used their Falcon ROV to remove the fiberglass grating and pull the cable end to deck for testing. Power and communications were still working, but heavy seas forced the crew to abandon the repositioning work. Then, in December 2010, Jonathan Zand and the SubOceanic crew returned to the site, found the cable end, moved it next to the platform and secured it with a 100lb weight.

Looking forward

We’re now eagerly working to get the Folger Pinnacle instruments commissioned so researchers can start using the data flowing from them. One team of researchers led by Sally Leys and Herb Yang of the University of Alberta will use the custom-built 8-lens camera system to make 3D images of sessile (non-mobile) suspension feeders living beneath the platform.

Other instruments will help scientists monitor plankton blooms, which could help explain variations in herring, and sockeye, chum and coho salmon productivity. Acoustic Doppler instruments will provide information on currents and waves in this VERY high energy environment.
