Science objectives

Obtain oceanic measurements from the north atlantic storm track to refine forecasting of upper-ocean shear set by the interaction of wind-forced near-inertial waves and mesoscale conditions. 

Science Activities

We will be deploying subsurface full depth ocean moorings (up to 3) which will be comprised of floatation, current meters, sensors to measure temperature, salinity and conductivity, acoustic releases and will be fixed to the bottom with an anchor.

The moorings will be placed at approximately 59.5 N, 26 W in 2700m depth, subject to modification but within our study area box of 58N, 28W; 61 N, 28W, 61 N, 23 W; 58 N, 23 W. These moorings will be recovered in fall 2020. Exact mooring locations to be determined in early April 2019.

Shipboard Equipment

ADCP 300 kHz
ADCP 150 kHz
A-Frame
Science Underway Seawater System
EM122 (12 kHz) Multibeam Echosounder
EK80 Sonar
Dynamic Positioning System
WAMOS
ADCP 38 kHz
Crane
EM710 MkII (40 to 100 kHz) Multibeam Echosounder


Shipboard Equipment Notes: We have also requested the TSE Spooler from the winch pool. 
We are requesting to use the shipboard system to ping our releases once the moorings are deployed if possible. Otherwise, we have our own deckset which we can also use.

Shipboard Communication

Basic Internet access via HiSeasNet


Shipboard Communication Notes: We will be receiving daily updated sea surface height imagery from PIs based in the USA and will need to download these.

CTD/Water Sampling

Wet Labs C*Star transmissometer (660nm wavelength)
SBE43 oxygen sensor
911+ Rosette 24-position, 10-liter bottle Rosette with dual T/C sensors
Biospherical underwater PAR (1000m depth limit) with reference Surface PAR
Wet Labs FLNTURTD Combination Flourometer and Turbidity Sensor

Critical CTD Sensors:  We do NOT need bottles but the regular CTD w/associated sensors.

MET Sensors

Barometric Pressure
Air temperature
Precipitation
Relative Humidity
Wind speed and direction
Short Wave Solar Radiation
Long Wave Solar Radiation
