Science objectives

This is a multidisciplinary study of the Middle Atlantic Bight outer shelf and upper slope south of New England with three science objectives:
1.) Study paleo hurricanes and other climate indices over the last 10,000 years with sediment cores collected over the outer shelf (Donnelly et al).
2.) Investigate biological community function by leveraging advances in metabolomics and proteomics to examine pelagic biogeochemical and biochemical cycling (Kujawinski et al).
3) Characterize the currents on the upper slope to examine the connectivity of the Slope Jet, its response to warm core rings, filaments and winds, and its role in mitigating shelf/open-ocean exchange processes (Andres et al).

Science Activities

To achieve these science objectives we will carry out the following activities on the cruise:

1.) Vibracore/Hurricane Study
(a) Core in the Mudpatch in water depths < 150 m where previous mapping suggests that the sediments record hurricane events. 
(b) Conduct further Chirp subbottom profiling to help target additional core locations.

2.) Clio AUV/Simultaneous Metabolomics and Proteomics
(a) Launch and recover Clio for ~10 hour missions for simultaneous metabolomic and proteomic sampling and to develop engineering protocols.
(b) Reserve some samples from Clio for future genomic testing. 
(b) Collect and process water samples with the CTD Rosette for cross-verification of Clio profiles.

3.) Science RoCS/Slope Jet
(a) Collect underway shipboard data in six transects across the 100-m to 3000-m isobaths along a 245-km stretch over the steeply sloped bathymetry spanning the 100-3000-m isobaths. Measure near-sruface temperature, salinity (TSG), velocity profiles (300, 150 and 38 kHz ADCPs), and weather data (Vaisala).
(b) Collect full-water column CTDs at the endpoints of these transects and at 3 midpoints.
(c) Support the development of Science Research on Commercial Ships (Science RoCS) by testing data collection and transmission protocols suitable  for a commercial vessel environment, including transmiting subsets of the various underway data streams to shore in real time with a prototype "RoCS Box."

Winches

Trawl Winch with 9/16th trawl wire

Winch Notes: Mike is going to check with the Armstrong for their suggestions for Clio's winch suggestion/needs.



Wire Notes: Jef's group will bring a chirp sonar, will go over the side (shallow) with the trawl wire. Vibracore will go over on trawl wire as well (most likely up to several hundred meters, but is capable of going ~3000 m).
