VAMPIRE_MOCNESS_Raw Dataset Description: Methods and Sampling: <p>In October 2024, the R/V Endeavor cruise EN723 was conducted on the US NE Shelf Break. The MOCNESS tow nets with 222 micron mesh were deployed from October 22-26th.&nbsp;MOCNESS sampling protocols included targeted vertical day night pairs whose depths were adapted to seafloor depth and canyon topography.&nbsp;</p>
<p>After collection different samples were preserved in formalin for later Zooscan analysis or dried as five size fractionated biomass (200, 500, 1000, 2000, 5000) samples.&nbsp;</p>
<p>The location of the cruise focused on part of the Atlantis Canyon, East area. The canyon has a strong bent mid-way, and in the upper part there is a bowl, and a very low sill closing this bowl form the exit to the bent. The tows were associated with some deployments with a lander that was placed to the NW of the bowl, at about 644 m depth. Other tows focused on canyons themselves.</p>

Collaborative Research: an autonomous profiling vehicle for concurrent acoustic, visual and environmental measurements in the mesopelagic ocean

Collaborative Research: an autonomous profiling vehicle for concurrent acoustic, visual and environmental measurements in the mesopelagic ocean
<p><em>NSF award abstract:</em><br />
The mesopelagic region of the ocean, between 200 and 1500 meters deep, is home to a complex mixture of physical processes, biological environments and animal communities that interact over a range of temporal and spatial scales. The mesopelagic remains poorly sampled due to the inherent limitations and asynchrony of measurements collected with ship-based instruments, acoustic surveys, remotely operated and towed vehicle systems. This project will develop a novel autonomous robotic instrument to collect physical, visual and acoustic data that will provide concurrent environmental, abundance, taxonomy and size structure data for animals ranging from 100 microns to 10 centimeters in size. The suite of sensors, coupled with a non-disruptive propulsion system and the operational flexibility of the new system will address critical knowledge gaps in our understanding of the ecology of the ocean's midwater zone. The vehicle will be tested on several cruises in the North Atlantic. The researchers will leverage the ongoing Bermuda Atlantic Time Series (BATS) datasets for cross-comparison and validation. This project will also create research opportunities for undergraduate and graduate students at the University of Rhode Island, Stony Brook University and the Bermuda Institute of Ocean Sciences (BIOS). Public outreach will be facilitated through a partnership with the William M. Davies, Jr. Career and Technical High School, the Rhode Island Teacher-At-Sea program and the BIOS Mid-Atlantic Robotics IN Education (MARINE) program. These activities will develop activities to support STEM education and Next Generation Science Standards.</p>
<p>The proposed instrument will be a stealthy vertical profiling vehicle. The sensor suite will consist of steerable multiple-frequency (38/70/200 kHz) broadband acoustics, stereo low light imaging, an Underwater Vision Profiler (UVP6), and environmental sensors for temperature, salinity, oxygen, chlorophyll, turbidity, beam attenuation and photosynthetically active radiation (PAR). Vertical propulsion will be achieved by an internal pumped volume ballasting system, which will create minimal disturbance around the vehicle to reduce avoidance behaviors known to bias observations from net tows and thruster-powered vehicles. Low light cameras will enable taxonomic documentation and size discrimination of larger organisms and gelatinous animals not quantitatively captured in net tows. The concurrent acoustics and environmental data will provide more complete habitat information than is possible with shipboard systems alone. With these capabilities the instrument will occupy an unfilled niche for sensing in the mesopelagic.</p>
<p>This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.</p>

PI Supplied Instrument Name: PI Supplied 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.

PI Supplied Instrument Name: MOCNESS system equipped with SIO electronics PI Supplied Instrument Description:Instrument Description: Environmental data was collected by a MOCNESS system equipped with SIO electronics (seabird 9 aboard, with connection through seabird 11 deck box). Sensors included Temperature, Pressure, Conductivity, Oxygen and a Fluorometer. Net itself was a 1-m2 MOCNESS equipped with 10 nets with 222 micron mesh. Instrument Name: MOCNESS Instrument Short Name:MOCNESS 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. There are currently 8 different sizes of MOCNESS in existence which are designed for capture of different size ranges of zooplankton and micro-nekton Each system is designated according to the size of the net mouth opening and in two cases, the number of nets it carries. The original MOCNESS (Wiebe et al, 1976) was a redesigned and improved version of a system described by Frost and McCrone (1974).
