Abstract
Ship sensor data collected along the track during R/V Seward Johnson cruise SJ9505 in the Gulf of Maine and Georges Bank in 1995 as part of the U.S. GLOBEC program (GB project)


Coverage

Spatial Extent: N:42.0019 E:-66.3169 S:40.53809 W:-70.1018
Temporal Extent: 1995-04-07 - 1995-04-19

Dataset Description

Seward Johnson Cruises: 9505
Shipboard meteorology and sea surface measurements
along the ship's track

Note:  As noted below, these data are uncalibrated and should be used accordingly.

These data are accessed under the the GLOBEC homepage-->data-->process-->{year}-->alongtrack
  1. These are stored as single ascii files per cruise with several variables merged to one minute (interpolated) time steps.
  2. The first column is the time stamp which, for Albatross convention, is "yrday0_gmt" which means, for example, that a time of "0.5" represents local noontime on Jan 1st.
  3. We all understand this data (shipboard temp, salt, wind, etc.) should be treated as uncalibrated records and should not be used other than exploratory purposes.

Generic Instrument Description
A thermosalinograph (TSG) is used to obtain a continuous record of sea surface temperature and salinity. On many research vessels the TSG is integrated into the ship's underway seawater sampling system and reported with the underway or alongtrack data.

Project Information

U.S. GLOBEC Georges Bank (GB)


Coverage: Georges Bank, Gulf of Maine, Northwest Atlantic Ocean


The U.S. GLOBEC Georges Bank Program is a large multi- disciplinary multi-year oceanographic effort. The proximate goal is to understand the population dynamics of key species on the Bank - Cod, Haddock, and two species of zooplankton (Calanus finmarchicus and Pseudocalanus) - in terms of their coupling to the physical environment and in terms of their predators and prey. The ultimate goal is to be able to predict changes in the distribution and abundance of these species as a result of changes in their physical and biotic environment as well as to anticipate how their populations might respond to climate change.

The effort is substantial, requiring broad-scale surveys of the entire Bank, and process studies which focus both on the links between the target species and their physical environment, and the determination of fundamental aspects of these species' life history (birth rates, growth rates, death rates, etc).

Equally important are the modelling efforts that are ongoing which seek to provide realistic predictions of the flow field and which utilize the life history information to produce an integrated view of the dynamics of the populations.

The U.S. GLOBEC Georges Bank Executive Committee (EXCO) provides program leadership and effective communication with the funding agencies.

Program Information

U.S. GLOBal ocean ECosystems dynamics (U.S. GLOBEC)


Coverage: Global


U.S. GLOBEC (GLOBal ocean ECosystems dynamics) is a research program organized by oceanographers and fisheries scientists to address the question of how global climate change may affect the abundance and production of animals in the sea.

The U.S. GLOBEC Program currently had major research efforts underway in the Georges Bank / Northwest Atlantic Region, and the Northeast Pacific (with components in the California Current and in the Coastal Gulf of Alaska). U.S. GLOBEC was a major contributor to International GLOBEC efforts in the Southern Ocean and Western Antarctic Peninsula (WAP).
