Science Objectives

The primary objective of the proposed March/April 2011 R/V Oceanus plankton imaging sampling cruise is to collect high-resolution data on plankton and marine snow together with environmental variables using the VPRII.  A high-speed survey of the shelf and slope waters of the northern Gulf of Mexico will be conducted, with the transect lines running through the standard SEAMAP stations and extending beyond them into the slope sea (Figure 2).  The occurrence, abundance, biomass, and vertical distribution of plankton and marine snow, together with ocean temperature, salinity, chlorophyll fluorescence, PAR, and turbidity in the Gulf of Mexico will be quantified in real time.  This sampling will allow direct comparison of data from traditional samplers used in the SEAMAP surveys and the current NRDA MOCNESS surveys with optical imaging of the VPRII.  The VPRII sampling will extend the spatial resolution of the present sampling and will allow quantification of fragile plankton and marine snow.  It will also allow comparison between deeper DAVPR optical-based sampling in the slope region with net-based sampling of shelf and slope regions.  The proposed Oceanus cruise is part of the over-arching plan to conduct sampling in each season, utilizing several sampling methods (e.g. MOCNESS, bongo net, neuston net, and imaging systems).  The duration of the program with respect to the number of years is to be determined.  Because plankton are transported over wide areas, and populations are connected across the northern Gulf of Mexico, sampling plans need to be broad in geographic scope. 

Science Activities

We wil conduct 10-knot surveys using the VPRII.  We will have 3 watches, 8-on and 16-off for the 24/7 ops.  We will start samping off Tampa and continue along the proposed grid until reaching Panama City, FL, on about March 19, where we will exchange some of the science party.  We then will continue the survey until reaching Galveston, TX on about April 9.
Shipboard ops will involve primarily towing the VPRII.  Depending on time, weather, VPRII malfunctions, we will also bring the DAVPR and the Holocam for sampling at fixed stations along the grid at depths up to 1000m.  These operations are considered as a backup plan to the main VPRII mission.  In the event we use the DAVPR/Holocam, we will have it mounted on a small CTD frame, with the DAVPR frame mounted to it.
