Arctic Ocean Circulation Patterns Affected by Climate Change

The University of Alaska Fairbanks International Arctic Research Center recently ran successful two-year deployments in the Arctic Ocean with McLane Moored Profilers (MMP) outfitted with Sea-Bird Moored Profiler CTDs. The deployments were part of the Nansen and Amundson Basins Observational System (NABOS-II) expedition. The MMP mooring data has helped compile a cohesive picture of the climatic changes in the Eurasian and Makarov basins of the Arctic Ocean. Observations from the mission are documented in the study Structure and variability of the boundary current in the Eurasian Basin of the Arctic Ocean, published in Deep-Sea Research I.
New observations provided a variety of insights into various processes and mechanisms driving changes in the Arctic Ocean. Seasonal and interannual changes in both circulation and temperature suggest that the region is heading toward a more dynamic state. The expedition was supported by grants from the National Science Foundation, National Oceanic and Atmospheric Administration and the Polar Research Programme of the Norwegian Research Council.
The McLane Moored Profiler (MMP) uses the SBE 52-MP Moored Profiler CTD to provide climate-quality temperature and salinity data, and can also be outfitted with other Sea-Bird Scientific sensors such as Sea-Bird Electronics Inductive Modem Instruments, Satlantic Suna Nitrate Sensor, Sea-Bird Electronics 43F Dissolved Oxygen Sensor, and WET Labs ECO and C-Star Sensors.

National Institute of Ocean Technology (NIOT) Team wins National Geoscience Award
The team at NIOT, comprised of Dr. R. Venkatesan, Scientist-G, Mr. M. Arul Muthiah, Scientist-D, Mr. B. Kesavakumar, Scientist-C, along with Dr. K. P. Krishnan, Scientist-D of National Centre for Ocean and Antarctic Research, has been selected for the prestigious National Geoscience Award by the Government of India for the successful installation of the Indian Moored Arctic Observatory (IndARC) in the Arctic.
The scientists installed a multi-sensor moored observatory in the Kongsfjorden Fjord, an inlet roughly half-way between Norway and the North Pole, in July 2014. IndARC collected more than 1 million data points between July 2014 and July 2015. Success of the deployment relied on the performance of numerous Sea-Bird Scientific instruments, including SBE 37-IMP-ODO CTDs, ECO-FLNTU chlorophyll and turbidity sensors, ECO-PAR radiometers and SUNA V2 nitrate sensors. The observatory was serviced and redeployed in July 2015.
Sea-Bird Scientific has a long history of working collaboratively with the Indian Ocean Science community and we look forward to strengthening these relationships by providing continued support.
Sea-Bird Scientific at Oceanology International in London Next Week
Sea-Bird Scientific is looking forward to exhibiting next week at London's Oi 2016. Sea-Bird Scientific will have several personnel on hand to meet with you and discuss your programs, applications and plans. Among those attending for Sea-Bird Scientific will be President Casey Moore, VP Ocean Research and Product Engineering Tom Mitchell, Chief Science Executive Norge Larson, Director of Sales Calvin Lwin and Director of Marketing Geoff MacIntyre. They and others will be available all week at Stand K100; to book a specific appointment, please go to Sea-Bird Scientific @ Oi16. Our UK partners Planet Ocean will also be exhibiting and available to discuss your needs, at Stand H500.
Optimistic Mood at the 2016 Ocean Sciences Meeting
Sea-Bird Scientific recently attended the 2016 Ocean Sciences Meeting in New Orleans. With more than 5000 participants from over 50 countries, the mood among scientists, administrators and vendors was much improved from recent meetings. Sea-Bird Scientific had a very busy week with posters, talks, social events and the trade show exhibit. After hundreds of conversations, the consensus reflection was very upbeat and optimistic. This was a welcome and positive change from recent OS meetings.

Scientific offers regularly
scheduled four-day training classes
approximately two times per year at
an off-site location near our office/factory
in Bellevue, Washington (12
miles from downtown Seattle). Through our
modules, we teach our customers how to get
the most from their
instruments. Training consists of operator
training on major Sea-Bird
Scientific products and software, and is
hands-on in nature. The curriculum covers
profiling instruments, thermosalinographs,
and moored instruments, and
includes theory and operation, data
processing, and maintenance and
repair. We encourage you to take advantage
of our expertise and
participate in our training classes. Our
next 4-day training classes are scheduled for May 16-19 and October 3-6,
Visit Sea-Bird University for more details, or contact Payal Parikh (firstname.lastname@example.org) to enroll.
Tech Tip: Deployment Orientation for Pumped SBE 37 MicroCATs
||Have you ever wondered about the 'Deploy This End Up' label on your MicroCAT? Sea-Bird's general recommendation is to deploy the MicroCAT as defined by that label; this places the plumbing in an inverted U-shape, to minimize the ingestion of sediment. A small bleed hole provides a way for air to exit the plumbing, so that the pump will prime and operate.
However, there are a few situations where you might want to consider other orientations:
- Deployments where severe bio-fouling is the main concern and sediment is not an issue.
- Deployments where air bubbles are the main concern and sediment is not an issue.
- Deployments where (for mounting reasons) the preferred orientation is not vertical.
Optimizing Data Quality / Deployment Orientation in Section 4 of your MicroCAT manual provides Sea-Bird's recommendations for dealing with these situations.
Note for pumped MicroCATs purchased prior to 2006: These MicroCATs did not have a bleed hole in the duct; recommendation is to deploy with a U-shape to the plumbing (i.e., 180 degrees off from the current design).

Director of Sales, Ocean Research Business Unit
Calvin Lwin, based at our Bellevue, Washington (Sea-Bird Electronics) site, received his Electrical Engineering degree from Santa Clara University, where he was on a team that built an underwater ROV for their senior design project that was used by NOAA's National Undersea Research Program. He started his professional career as a Technical Sales Engineer in the semi-conductor industry. He later found an opportunity in the marine industry and was Sales Manager for a company that supplied equipment to the ROV market. A fortunate encounter with one of Sea-Bird's previous owners brought him to Sea-Bird Electronics 10 year ago, where he started as an Applications Engineer.
Calvin is now Director of Sales for Sea-Bird Scientific's Ocean Research Business Unit, working with his team of Sales/Applications Engineers and international sales representatives to consult with customers and recommend the best sensor solutions suited for specific applications.
Calvin has two active kids keeping him and his wife very busy. He enjoys coaching his daughter's soccer team and playing sports with his son.
