|Scallop “recruits” abundant on Georges Bank
The SMAST scallop video survey team reported its 2014 findings to the Fishermen’s Steering Committee last week: populations are up, particularly the numbers of small scallops and particularly on Georges Bank.
“The overall stock biomass measured in scallop meat weight is estimated to be 320 million lbs, a substantial increase from the 243 million lbs observed in 2012,” said SMAST Prof. Kevin Stokesbury, lead scientist of the annual video survey. “However, the extraordinary news is the huge number of new recruits, small scallops less than 3 inches that will reach commercial size in the next few years.”
The US sea scallop resource averages 8 billion animals, but large increases in scallop populations seem to occur once every 10 years or so. A population spike from 2003 has supported a large part of the fishery for the past 10 years. The increase seen this year on Georges Bank is even larger than that of 2003, increasing the total estimated resource to 26 billion scallops.
“If protected and managed correctly,” said Stokesbury, “these scallops could insure sustainable catches for the next decade similar to those over the past 10 years.”
The video survey was conducted this year from May to July cooperatively with the fishing industry.
|NOAA, state fund SMAST fisheries research
Recent awards totaling nearly $5 million from NOAA and the Commonwealth of Massachusetts will fund SMAST scallop and groundfish research over the next two years.
The National Oceanic and Atmospheric Administration has announced cooperative fisheries research projects, including four led by SMAST scientists, to be funded under the "2014-2015 Sea Scallop Research Set-Aside Program
. The RSA Program reserves a portion of the scallop harvest to fund cooperative research of benefit to the fishery.
Department of Fisheries Oceanography Chair Kevin Stokesbury is principal investigator on two funded video surveys and a project to track so-called "gray meat" in sea scallops, while Professor Steven Cadrin will continue as PI of the highly successful SMAST Yellowtail Bycatch Avoidance Program
. The four projects total $4.4 million. In addition, SMAST researchers are co-investigators on two RSA projects led by collaborating institutions.
A separate award of $450 thousand from the state was announced at a press conference at SMAST on 21 July attended by (from left in photo

Antonio Cabral (D-New Bedford), UMass Dartmouth Chancellor Divina Grossman, state Senator Mark Montigny (D-New Bedford), and SMAST Dean Steven Lohrenz. The funding will support the continued development of new "no-capture" technology for fishery population surveys. The elected officials in attendance were instrumental in securing the state funding.

|UMass launches lidar center
Profs. Miles Sundermeyer and Brian Howes of SMAST are among the principals of a new UMass system-wide EXperimental Center for Environmental Lidar (EXCEL), which has been established with a $150K grant from the University's 2014 Science and Technology Initiatives Fund.
Lidar (Light Detection and Ranging) is a remarkably precise remote measurement technology that has applications in a wide range of the natural sciences, and is a tool in research initiatives already underway on the Amherst, Boston, Dartmouth, and Lowell campuses.
"By sending extremely short pulses of light (nanoseconds in duration), researchers can image objects and landscapes in three dimensions with meter-to-centimeter resolution," explained Sundermeyer. "Mounted on a tripod, a boat, or even an aircraft, lidar can be deployed rapidly in the field to image forests, coastal land-forms, and even shallow underwater landscapes."
Of particular interest to SMAST researchers are the oceanographic applications of lidar. Coastal erosion, both as a chronic issue associated with sea level rise and as a result of episodic extreme events such as Hurricane Sandy in 2012 or the blizzard of 2013, will have increasing impact on the state’s economy.
"Our ability to make rapid and precise measurements of coastal landforms and flora will be a critical tool in the maintenance of our coastal resources, and therefore of ecosystem health and coastal tourism," said Sundermeyer. "EXCEL is expected to accelerate these capabilities, while providing a technical resource and expertise to the Commonwealth, the region, and beyond."
|UMassD scientists join US-India collaboration
UMass Dartmouth Prof. Amit Tandon (College of Engineering/SMAST) is leading a first-of-its-kind collaboration between the United States and India to support large-scale research on monsoon prediction.
Researchers from the two countries are working together to understand ocean processes in the international waters of the Bay of Bengal and their relation to the annual monsoon, which is a dominant factor in the lives of the population of the Indian subcontinent.
The Office of Naval Research is funding the participating U.S. scientists and contributing the resources of the R/V Roger Revelle
. The ship made a call in the port of Chennai in mid-June, the first U.S. research vessel to call at an Indian port since the 1980s, and has since completed its first successful data-gathering cruise in the Bay of Bengal.
The bilateral team also includes Dr. Amala Mahadevan, WHOI senior scientist and SMAST adjunct faculty, Dr. Sanjiv Ramachandran, research associate in Tandon’s Upper Ocean Dynamics Lab, and scientists from 17 other U.S. and Indian institutions.
As part of the collaboration, Dr. Tandon and several U.S. colleagues have returned to India to conduct a two-week training workshop at the Indian Institute of Science Bangalore on upper-ocean dynamics in the Bay of Bengal. [Read full press release.] Photo: Amit Tandon welcomes scientists aboard the

|Final port recovery plan released
New Bedford Mayor John Mitchell and State Senator Mark Montigny visited SMAST on June 17 for a press conference to announce the release of the final "Groundfish Port Recovery and Revitalization Plan for the Port of New Bedford/Fairhaven
The study was conducted by an SMAST-led research team fronted by Prof. Dan Georgianna (Economics/SMAST). The report documents the recent decline of the regional groundfishery, assesses its effects on shoreside businesses, and makes recommendations for the revitalization of the fishery and improvements to the port.
"New Bedford is the nation's number one fishing port," said Mayor Mitchell, "and we intend to keep it that way for the next hundred years. … To do that, we need the best science in stock surveys and assessments—that is critical for both scallops and groundfish."
"I applaud the work of Dan Georgianna and his colleagues at the School for Marine Science and Technology at the University of Massachusetts, Dartmouth, in compiling this report," said Senator Montigny, who was instrumental in securing funds for the study through the state legislature. "We must do all we can to maintain New Bedford's economic contribution as the highest value catch port in the U.S."[Reposted from July 1, 2014]
