MOCNESS CTD data from the Gulf of Maine Krill project Dataset Description: <p>CTD data collected during the 1 meter2 MOCNESS tows for three cruises in 2010 to the Gulf of Maine and Georges Bank. &nbsp; These data provide standard environmental measurements simultaneously with the collection of the animals.</p>
<p>Fluorescence, oxygen and irradiance data were not collected on these cruises.</p> Methods and Sampling: <p>&nbsp;From the MOCNESS Operating Instruction Manual: &nbsp;&quot;The nets are opened and closed sequentially by commands through a single conductor armored cable from the surface. &nbsp;The electronics has 16-bits of resolution and the basic data stream consists of temperature, depth, conductivity, frame angle, flow counts, net number and net response. &nbsp;An acquisition/controller computer retrieves data from the underwater unit at a rate of up to 4 times a second. &nbsp; Temperature (to approximately 0.01 deg C) and conductivity are measured with SEABIRD sensors. &nbsp;A modified T.S.K. flowmeter is normally used to measure flow past the net. &nbsp;Both the temperature and salinity sensors and the flowmeter are attached to brackets which are mounted on the top portion of the frame so that they face directly into the flow when the frame is at a towing angle of 45 deg. &nbsp;An electronic pendulum angle transducer measures the angle of the towed net through the water. &nbsp;A GPS unit providing latitude and longitude [is] integrated &nbsp;into the data stream.&quot; &nbsp;(p. 7)</p>

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>

from Cruise: EN487 <div>Both the VPR and MOCNESS were deployed via the stern A-frame using winch #2. Although the VPR is autonomous and does not require conducting cable, for this cruise we had borrowed Dr. Mark Baumgartner’s VPR, which includes a full CTD. We therefore wired up this CTD through the winch in order to get real-time information on depth and altitude, and to use (or try to use) Mark’s bottom switch. This required some initial fiddling with baudrate and sampling intervals, but communication worked fine.</div>
<div> </div>
<div>The MOCNESS communicated with the deck unit fine with the ca. 10,000m of wire on winch #2.</div>
from Cruise: EN484 <div>A standard 1m2 Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) was used to collect zooplankton in order to determine the taxonomic composition of the zooplankton in the study region and also to ground truth acoustic data collected with the HTI multi-frequency and Edgetech broadband systems. </div>
<div> </div>
<div> The underwater unit used was #169.</div>
<div> </div>
<div>
<div>In addition to the standard temperature and conductivity probes the system also had a beta-type strobelight unit for reducing avoidance of the nets by some zooplankton, notably krill, and possibly small fish.</div>

<p>To continue from the MOCNESS Manual: &nbsp;&quot; A microcomputer (together with disk drive and printer) are the deck unit and permit shipboard real-time data acquisition and processing as well as net control. &nbsp;Salinity (to approximately 0.01 ppt), net oblique velocity and vertical velocity, and volume filtered by each net is calculated after each string of data has been received by the computer. &nbsp;Raw and processed data are stored on disc (in separate files) and processed data can be printed out. &nbsp;Plots of net depth versus time, temperature and salinity versus depth, temperature versus salinity and latitude versus longitude are made during a tow and displayed on the computer screen.&quot; &nbsp; &nbsp;(p. 7)</p>

CTD MOCNESS
CTD MOCNESS
PI Supplied Instrument Name: CTD MOCNESS Instrument Name: CTD MOCNESS Instrument Short Name:CTD MOCNESS Instrument Description: The CTD part of the MOCNESS includes 1) a pressure (depth) sensor which is a thermally isolated titanium strain gauge with a standard range of 0-5000 decibars full scale, 2) A Sea Bird temperature sensor whose frequency output is measured and sent to the surface for logging and conversion to temperature by the software in the MOCNESS computer (The system allows better than 1 milli-degree resolution at 10 Hz sampling rate), and 3) A Sea Bird conductivity sensor whose output frequency is measured and sent to the surface for logging and conversion to conductivity by the software in the computer (The system allows better than 1 micro mho/cm at 10 Hz sampling rate). The data rate depends on the speed of the computer and the quality of the cable. With a good cable, the system can operate at 2400 baud, sampling all variables at 2 times per second. One sample every 4 seconds is the default, although the hardware can operate much faster. (From The MOCNESS Manual) Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/131/
