Primary Objectives a. Assess the occurrence, abundance and geographical distribution of the early life stages of fall spawning fishes, especially king and Spanish mackerel, red drum, and snappers, on U.S. continental shelf waters in the GOM using a 61 cm bongo frame fitted with 0.335 mm nets, and a 1x2 m neuston frame fitted with a 0.950 mm net at selected Southeast Area Monitoring and Assessment Program (SEAMAP) stations in support of annual stock assessments. b. Describe the pelagic habitat of fish larvae through measurements of various physical and biological parameters: i. Record profiles through the water column of temperature, salinity, fluorescence, dissolved oxygen, and turbidity using a CTD at SEAMAP stations. ii. Measure chlorophyll a in replicate water samples taken at surface, maximum chlorophyll layer and near bottom (to a maximum of 200 m) depths using bench top fluorometry. iii. Detect and measure frontal features along the survey cruise track using data from the ship’s Fluoro-thermosalinograph flow-through system (TSG). c. Map the distribution of fish eggs and invertebrate zooplankton along the cruise track using a Continuous Underway Fish Egg Sampler (CUFES). d. Measure the vertical distribution of fish larvae by sampling at discrete depths in the water column at selected locations along the SEAMAP plankton survey grid using a 1 m Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) during both legs of the survey. 2 Template Date: 25SEP2020 e. Collect detailed observations of net-caught jellyfish and ctenophores. 2. Secondary Objectives a. Assess the occurrence and abundance of marine debris and microplastics in the GOM in collaboration with the NOAA Marine Debris Program. b. Collect zooplankton samples for a University of Florida graduate student project examining temporal stability of the isotopic baseline across the Gulf of Mexico.

Based on more than 60 years of research and development in close collaboration with leading marine scientists this wide band echo sounder system has succeeded the famous EK60, which became an international standard for fish stock assessment. The Simrad EK80 can operate a large number of frequencies simultaneously ranging from 10 to 500 kHz. A wide selection of high quality accurate transducers is available. GU2203_EK80 completed NOAA Ship Gordon Gunter Gunter 2013-04-09 creation Gordon Gunter (GU) The NOAA Ship Gordon Gunter primarily serves the National Marine Fisheries Service (NMFS), assisting NMFS in accomplishing its responsibilities for conserving and managing our Nation's living marine resources. The ship's homeport is located at the NMFS Pascagoula Laboratory in Pascagoula, Mississippi. The Gordon Gunter operates primarily in the waters of the Gulf of Mexico, Atlantic Ocean, and Caribbean Sea. The ship conducts scientific surveys of the health and abundance of fishery resources and marine mammals. The vessel is operated by NOAA Marine and Aviation Operations.
