eMolt Session Shows How Long-term Collaboration Pays off

This afternoon  I had a chance to listen in on Jim Manning’s discussion of eMolt at the forum. A diverse audience of 20+ fishermen, scientists, technologists, and managers attended. The eMOLT program has grown from a small collaboration with lobstermen to a wide array of collaborative projects with various industry sectors, educational programs, and scientists. Jim provided an overview of the various projects and asked collaborators to discuss their perspectives. The value of collaborative research and data collection was discussed at length and numerous ideas were developed for improvements to current projects and new projects that would be worth pursuing.

Right Whales Sound Off

On Tuesday this week, I got a chance to go out with a crew from Woods Hole Oceanographic Institution aboard their research vessel (R/V)  TiogaWe searched for North Atlantic right whales, towed for plankton, and deployed both a slocum glider and an underwater microphone called a hydrophone.  Just last week a crew from the center spotted more than a dozen whales in the same area we worked in, where there is also a  moored listening station that captures the sounds made by several species of large whales when they are present. WHOI, our center,  and the US Coast Guard are collaborating on the project.

The moored digital acoustic monitoring –DMON for short– buoy includes a real-time detection system and hydrophones that listen for and record the vocalizations, or “calls”of four kinds of baleen whales: sei, finback, humpback, and the highly endangered North Atlantic right whale. The hydrophones record around the clock. Snippets of the recordings are sent back to shore every two hours.  Eventually all the data are retrieved and then analyzed by experts who can identify which species of whale made the sounds..

We also deployed a WHOI slocum glider, an underwater robot that can also detect and record whale calls.  The recordings are  transmitted by satellite phone to a computer onshore that also helps navigate the glider from point to point.   The glider powers its way up and down in the water for two to three weeks on a set of alkaline batteries.

These projects are examples of how NOAA scientists are collaborating with biologists and engineers to increase our understanding of the marine environment using state of the art technology.  Although we didn’t find any right whales, it was a beautiful day on the water and I enjoyed learning about research underway by WHOI scientists.

A break in the weather, and success

It is Tuesday night (Feb. 21) and the NOAA vessel Henry Bigelow is leaving Georges Bank and working into the western Gulf of Maine area for the last part of the Winter Ecosystem Monitoring Survey (EcoMon).

Although dogged by rugged weather from the day before sailing, the ship has managed to complete over a hundred stations so far, from Chesapeake Bay to the Gulf of Maine, and will have a grand total of about 114 stations prior to the time we dock in Newport, RI on Thursday morning (Feb 23).

The weather has given us a break at a key juncture in the cruise, as we were heading out to Georges Bank, which is a notoriously unforgiving area during this time of the year.  That break in the weather, combined with an exceptional effort on the part of the crew and command of this vessel, has helped turn this trip into a resounding success, despite the fact that a blizzard delayed the arrival of our science team and caused us to sail a day late.

I’d like to thank the key parties involved in contributing to this success: the CO and command on the vessel were constantly coming up with suggestions and cruise track “tweaks” to help us cover the survey area as quickly as possible despite the conditions.  The crew, who were always at the ready to get the gear deployed “efficiently and safely” to quote our chief boatswain, plus the engineers and electronics specialist who kept the ship running and sampling flawlessly (no downtime on this trip!) and the stewards who not only kept us fed, but kept up morale with ice cream socials on Sunday nights!  Finally the science team, a diverse group with researchers from the Canadian Wildlife Service, UNH, EPA, the NEFSC, plus support from WHOI and the onboard Survey Techs who worked alongside us to collect hundreds of plankton samples and associated data.

Thank you all.  It was truly a pleasure to sail with you!

Gulls and Gannets

More news from  Chief Scientist Jerry Prezioso aboard the Bigelow on the HB1701 Winter Ecosystem Monitoring Survey (EcoMon):

Our Canadian Wildlife Service Seabird and marine mammal observer, Holly Hogan, has been steadily working through all these conditions, and has provided a brief summary of what she’s seen so far.  Here is her update:

“Here’s a little flavour of what’s been going on at the surface!

Northern Gannets have been seen on all days of the cruise so far.  As far as gulls go, there have been the usual suspects, seen regularly: Herring Gull and Great Black-backed Gull.

On the day we left port at Newport (February 11), there were Northern Gannets, and some of the alcids that you expect in the northern parts of the cruise: Common Murre and Atlantic Puffin.
On Feb. 12, Northern Gannets were common all day. When we were closer to shore there were Common Loons and even a Black Scoter, a seaduck normally associated with coastal waters.  Common Murres were seen again as well.
Feb. 13 was a stormy day.  Sightings on the surface would be difficult; you always miss things in these conditions.  However, there were many Northern Gannets seen, especially near the shelf edge.  There was also a Red-throated Loon seen, which is smaller and more delicate than Common Loons.
On Feb.14 there were Northern Gannets and some of the alcids as well: Two Dovekies (a tiny seabird that breeds in the high arctic) and Atlantic Puffin. Common Dolphins were also seen in small groups.
On February 15, the water was calm for the whole day – excellent observing conditions. Northern Gannets were by far the most common species seen. Common Loons were also seen regularly.  The shipping lanes to New York City were pretty quiet for seabirds.  There was one alcid species seen: One lone razorbill.  It may not have been well, as it did not try to fly or dive from the ship, the normal behavior when the ship is in close range.  There were also excellent whale sightings:  A total of three fin whales, one humpback and one minke were observed.
So far today it’s been gull and gannets.  Lots of day ahead though!”

Bongos and Valentines

Hello All,

Today, February 16, finds us finishing up the Southern New England area, sampling at the last stations located in the eastern part of this region. After sailing north and out of a strong front that hit us around the Chesapeake Bay entrance, we made excellent progress on Valentine’s Day northward up to Southern New England waters. Another front came through with 40-knot winds just as we were working our way inshore from the shelf edge late last night and early this morning.  By deploying a smaller array of just the large bongo nets, rather than the typical large and small bongo frame combination, we were able to keep working through the worst of it at two offshore stations. We are now picking up some inshore stations before turning back offshore and on out to Georges Bank, something we hope to be able to do early tomorrow.

The vessel and crew continue to perform flawlessly, and there is an excellent rapport between the scientists, crew and command that is helping to make this trip much less of an ordeal despite the typical February cold and rough sea conditions. Our Third Mate Dana Mancinelli and Seabird Observer Holly Hogan went so far as to put out little Valentine cards and chocolate hearts to boost our spirits!

This may be a challenging trip due to the weather, but it is certainly a pleasure to work with this upbeat group!

Working in Windy Winter Weather …

The Henry Bigelow sailed from the snow covered Newport Naval Station Pier 2 on Saturday morning, February 11, at 0900 hours.  The diminishing seas from the strong blizzard winds of the day before allowed us to make our way out of Narragansett Bay to the shelf edge slope waters and southward before the next front caught up with us.  Luckily, we were able to complete eighteen stations before that happened by turning inshore to continue working as long as we could.

We are now off the coast of Virginia and slowly getting back to work as the 40-knot winds we experienced last night come down.  Our plan is to steam slowly offshore from the entrance to Chesapeake Bay as diminishing winds and seas  enable us to start back north, pick up two missed stations and then continue on to sample at our offshore stations.

This cruise was originally scheduled to start on Friday, February 9, but the blizzard that struck Rhode Island disrupted the travel plans of scientists joining us from the University New Hampshire and the Canadian Wildlife Service in Newfoundland.  We are attempting to make the best use of our remaining time by eliminating the southernmost part of the cruise track off of Cape Hatteras, giving us a chance to get to more northern areas like Georges Bank and the Gulf of Maine at the end of the survey.

The plankton catches have been light and dominated at most stations by copepods and chaetognaths (arrow worms); pretty typical for this time of year.  There were some salps in a couple of tows, which I was surprised to see, and one tow had a considerable amount of diatoms which were caught in the 165 micron mesh nets of our small bongos, but easily passed through the 333 micron mesh nets of the large bongos.   Images from the Imaging FlowCytoBot showed them to be pillbox shaped diatoms, like the genus Coscinodiscus.  Since we have been close to shore for much of this cruise, the three shallow water rosette casts we have made have shown temperatures and salinities to be very well mixed in the water column.

All equipment and the ship are fully functional, and people are in good spirits.  We just need some breaks in the weather now to make this a productive trip!

Small Science Staff, Lots to Accomplish

The NOAA vessel Pisces set sail from a busy Davisville, Rhode Island pier on Tuesday (Oct. 18) morning at 1030, flanked by a fleet of imported vehicles newly unloaded from two huge car carrying vessels docked nearby.

Our first task of the day was to undertake a calibration of the EK60 acoustic system on board, which was carried out by Mike Jech and his team while we anchored in the lower part of Narragansett Bay. The process took six hours and involved moving a tungsten carbide sphere under the hull and measuring the acoustic returns from the system.

The sphere got hung up at one point but the team was able to free it and get it back to continue the process, until it was finally completed at 1830 hours. By 1900 the team members, Mike Jech, Joe Godlewski and Jennifer Johnson, and all their gear were ferried ashore in a rigid hull inflatable launch to the Newport Naval Station located across the bay from our anchorage.

After the return of the launch we proceeded out of the bay to start the southern leg of our survey. Our mission is to continue the core monitoring program of gathering data on hydrographic and biological parameters of continental shelf waters, by means of electronic sensors, plankton tows and water casts. Unlike previous missions we have a very small scientific staff on this trip, with just two people on each 12 hour watch, but all our routine sampling will be carried out, including plankton sampling, dissolved inorganic carbon (DIC) sampling to track ocean acidity, and chlorophyll and nutrient measurements.

We also have an Imaging FlowCytoBot unit from Woods Hole Oceanographic Institution on board to photograph dinoflagellates, diatoms and marine protozoa that are picked up by the scientific seawater system of the vessel. The only difference from past surveys is that we have no outside researchers joining us. Even the Canadian Wildlife Service, which normally sends an observer to monitor seabirds and marine mammals, was unable to place someone on-board until the northern leg of this survey.

For now we are heading south, and at the moment of this writing, are approaching the outer edge of the continental shelf about 90 miles southeast from the mouth of Narragansett Bay. Weather for the next couple of days is looking good, so we’re expecting to make good progress, having already completed four plankton tow stations, and one water sampling station.
