EK80 Water Column Sonar Data Collected During GU2104
1. 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. 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 the NOAA Marine
Debris Program in the GOM
