Biological and Physical Determinants of Euphausiid Aggregation, Behavior, and Interaction with Higher Predators at an Abrupt Topographical Feature in the Gulf of Maine
https://osprey.bco-dmo.org/project/2129
Biological and Physical Determinants of Euphausiid Aggregation, Behavior, and Interaction with Higher Predators at an Abrupt Topographical Feature in the Gulf of Maine
<p>from the NSF award abstract:</p>
<h3>Distribution, Aggregation, and Ecological Importance of Euphausids in the Gulf of Maine Region</h3>
<p>Zooplankton are key members of marine ecosystems, but the biological and physical factors governing their distribution and aggregation are not fully understood, especially at the continental shelf break and margins of the deep basins of the shelf. Euphausiids are an important group of crustacean zooplankton in North Atlantic pelagic food webs and represent an interesting model species for the study of zooplankton aggregation due to their strong swimming capabilities and active aggregative behaviors. This project will address the hypotheses that the formation and variability of euphausiid aggregations along the northern flank of Georges Bank and the southern portion of the Gulf of Maine during fall relate to the interaction of physical concentration mechanisms with local topography and with plasticity in diel vertical migration and active aggregative behaviors, and that this plasticity arises from variability in food availability and predation by herring. These hypotheses will be addressed through a field program employing a comprehensive array of sensors, including both conventional narrowband and recently-developed broadband acoustic systems to sample the euphausiids, and a variety of other acoustic, optical, net, and other sampling devices to quantify their physical and biological environment. These sensors will be used in an inventive combination of (1) coarse-scale grid surveys to characterize along- and across-slope variability in the distribution of euphausiids, their predators, other zooplankton, phytoplankton, and physical conditions (e.g., the flow field), and (2) fine-scale adaptive surveys used to track individual euphausiid aggregations and observe how their three-dimensional structure and vertical position vary with changing environmental conditions. Repeat surveys will be timed to capitalize on known or likely variations in the flow field, food availability, light levels, and predation.</p>

Revised MOCNESS files for recomputed volumes using new flow meter calibration value determined on R/V Connecticut and R/V Endeavor (EN487). See write-up decribing the calibration procedure in EN487 cruise report. The volume revisions were done by Peter Wiebe using a flow meter calibration value of 6.41, which was the average of the values determined on the two cruises. The following is a list of the files used (raw) and produced (pro, tab) to compute the volumes filtered.</p>

18Nov2010 - modified M_01_002.raw to eliminate start and end data when net out of the water and also removed the &quot;#increment_net&quot; indicator for net 2 because it apparently did not open at the 600 m mark. Net 8 was opened at the surface and taking out this indicator provides the volumes for the towing scenario indicated on the log sheets.<br />

18Nov2010 - modified M_01_003.raw to eliminate end data when net out of the water and also modifed the &quot;#increment_net&quot; indicator in all cases so that the postprocessing would ignore the indicator. In addition all of the &quot;+&quot; indicators were changed to &quot;-&quot; to prevent spurious net number changes in the raw file from indicating a net bar had been dropped except that a &quot;+&quot; was added at the end of the raw file along with an &quot;#increment_net&quot; indicator to make the program calculate the total volume filtered for the tow. This was done because none of the nets were opened or closed on the tow. See log notes for additional details.<br />

MOCNESS1
MOCNESS1
PI Supplied Instrument Name: MOCNESS1 Instrument Name: MOCNESS1 Instrument Short Name:MOC1 Instrument Description: The Multiple Opening/Closing Net and Environmental Sensing System or MOCNESS is a family of net systems based on the Tucker Trawl principle. The MOCNESS-1 carries nine 1-m2 nets usually of 335 micrometer mesh and is intended for use with the macrozooplankton. All nets are black to reduce contrast with the background. A motor/toggle release assembly is mounted on the top portion of the frame and stainless steel cables with swaged fittings are used to attach the net bar to the toggle release. A stepping motor in a pressure compensated case filled with oil turns the escapement crankshaft of the toggle release which sequentially releases the nets to an open then closed position on command from the surface. -- from the MOCNESS Operations Manual (1999 + 2003).
