Operations focused on continental shelf and shelf-break waters between the NC-VA border and St. Lucie Inlet, Florida, between 18-200 m deep. Leg 1 consisted entirely of sonar mapping during the ship's northward transit, beginning at St. Lucie Inlet, FL. On legs 2 and 3, we deploy traps with attached video cameras at a variety of stations in the U.S. South Atlantic. Traps have a single line connected to two surface buoys. On legs 2 and 3, vessel operations will occur over a 24-hour workday. Trapping, video, hook-and-line sampling, and CTD operations will occur from approximately 0700 to approximately 1900 each day, during which time at least three vessel crew members will be needed on deck. We will use the time between 1900 and 0700 each day for transit to the next day’s sampling stations, multibeam sonar mapping, or for hook-and-line sampling. We will also be continuously running the calibrated EK-80 to collect acoustics data for fish during trap deployment and retrieval. The FPC has already supplied the ship with GPS points of most trap/video sampling locations, and trap sampling will commence at approximately 0700 each morning. We expect that six traps will be deployed off the stern of Pisces (down the stern ramp while the vessel is traveling at approximately 4.5 kt) over the course of approximately 20 min, one trap being deployed at a time and no closer than 200 m from another trap. After a group of six traps are deployed in an area, a single CTD cast will be conducted, and then traps will be retrieved after each trap has soaked for approximately 90 min (but no more than 150 min).

Operations focused on continental shelf and shelf-break waters between North Carolina and St. Lucie Inlet, Florida, between 18 and 200 m deep. Leg 1 took place July 4 through 16 (13 DAS).

A total of 63 sites were targeted for sampling over a period of twelve days. At each station, a Craib corer was deployed, and a relatively undisturbed surface sediment core collected with a penetration depth of about 6-10 cm deep. The core was extruded onboard and sectioned into two layers; the top 0-1 cm and the underlying 1-3 cm layers. Two 5cc subsamples were collected from the 0-1 cm layer for cyst counting (by microscopy) and for molecular analysis (via qPCR). The remaining sediment from the 0-1 cm layer, and the sediment from the 1-3 cm layer were refrigerated and retained for later processing (if needed). Sediment below 3 cm deep in the core was discarded. The two 5cc subsamples were processed onboard using standard cyst techniques, including protocols for dilution of the raw sediment, sonifying and sieving the sample to yield a 20-100 μm particulate fraction. One subsample was initially preserved in 2% formalin for subsequent exchange onboard into 100% methanol until later counting at the Beaufort Lab. The second subsample was centrifuged to remove the overlying water and frozen pending analysis in Beaufort. At up to six stations (to be determined), additional sediment was collected using the Craib corer for a method development project. At each station, a CTD provided by the ship was deployed to measure parameters such as salinity, pressure, chlorophyll, and temperature from the surface of the water to the bottom to characterize water masses moving within the Gulf of Maine.

Between 30 May - 12 June 2021, we will conduct Remotely Operated Vehicle (ROV) and multibeam sonar surveys inside and outside six marine protected areas (MPAs) as well as inside and outside the Oculina Experimental Closed Area (OECA) in the south Atlantic to assess the efficacy of this management tool to protect species of the snapper grouper complex and Oculina coral. We will also investigate two additional spots of interest: Devil’s Hole Spawning Management Zone and Cape Lookout. The cruise is planned for the continental shelf edge of the South Atlantic Bight between Port Canaveral, FL and Cape Lookout, NC. We will be working in and around the following six MPAs, Oculina Experimental Closed Area, and two additional areas of interest (Figure 1): Florida MPA: Northwest corner at 30°29' N, 80°14' W; northeast corner at 30°29' N, 80°2' W; southwest corner at 30°19' N, 80°14' W; and southeast corner at 30°19' N, 80°2' W.

The goal of the cruise is to gather additional data on habitat and fish assemblages in six of the South Atlantic MPAs and OECA as part of a long term sampling program to document changes in these areas before and after fishing restrictions are implemented. The southernmost boundary of our work areas will be Port Canaveral, FL while the northernmost boundary will be Cape Lookout, NC. Efficacy testing of this management tool will aid fishery managers in future use of area restrictions for the protection of valuable habitat and fishery resources. Specific objectives include: Daytime Operation: Conduct ROV transect surveys of habitat and fish assemblages and collections of corals and sponges during daylight hours. Night Operation: Conduct multibeam mapping to find areas to dive on with the ROV the following day. Night Operation: Conduct total water column CTD profiles and XBT casts to collect sound velocity data for the mapping

The Ecosystem Monitoring (aka Ecomon) survery uses bongo and CTD sampling to monitor and map the distribution of zooplankton, krill and smaller organisms) and the physical environment. The survey has been conducted four times per year (although fewer times in recent years) in each season on the continental shelf from Cape Hatteras, NC to the Canadian waters of New Brunswick and Nova Scotia. Acoustic data are occasionally collected. Marine mammal and bird observations have been collected in the past.

During the PC-18-03 cruise, four moorings were turned around, whereby existing moorings and their instrumentation were recovered, and replaced by new and identical mooring at the same or a nearby location. The first work area is located in the northwestern tropical Atlantic ocean and includes the Northwest Tropical Atlantic Site (NTAS), which is occupied by a surface mooring, and the nearby Meridional Overturning Variability Experiment (MOVE) 1 site, occupied by a subsurface mooring. The second work area is closer to the Caribbean islands and includes two subsurface moorings at the MOVE 3 and 4 sites. NTAS is operated and serviced by the Upper Ocean Processes (UOP) group from the Woods Hole Oceanographic Institution (WHOI). All MOVE moorings are operated and serviced by the Scripps Institution of Oceanography (SIO). For calibration purposes, comparison between measurements from moorings and ship were made during the turn around cruise. ARGO floats were also be deployed during transit out of Mayport towards the NTAS site. R/V Pisces departed Mayport FL on May 30 and returned to Morehead City NC on June 21 2018.

The survey consisted of 155 random-stratified and fixed Oceanography stations in the Middle Atlantic Bight, Southern New England, Georges Bank and the Gulf of Maine. The principal objective of the survey was to assess the hydrographic, planktonic and pelagic components of the Northeast U.S. Continental Shelf Ecosystem. Specifically, the spatial distribution of the following parameters: water currents, water properties, phytoplankton, microzooplankton, mesozooplankton, seabirds, sea turtles and marine mammals were quantified. Traditional and novel techniques and instruments were used. A broad array of measurements of the pelagic ecosystem were made during the October 15-30, 2021 cruise.

Both legs of the cruise focused on chevron fish trap and underwater video camera deployments, and Leg 1 of the cruise also included sonar mapping operations. Traps with attached video cameras were deployed at a variety of stations in the U.S. South Atlantic. Traps had a single line connected to two surface buoys. Multibeam echosounder (ME70) and XBT/CTD data collection operations were carried out at night, and all other operations (trapping with attached underwater video and CTD) during the day, with the exception of split-beam (EK60) surveys, which were carried out during both day and night.
