Description

GLOBEC Georges Bank Long-term Moored Array Component

CREST Mooring Site
41 24.461 N, 67 32.538 W

This deployment was between Apr 2, 1995 and Sep 30, 1995.

During this deployment the transmissometer record appears to decline at a steady rate during mid-record. This maybe due to biofouling, but this trend does not appear in the fluorometer.

Instruments

Rotronics Temperature and Humidity Probe

Supplied Name: Rotronics

Supplied Description:

Air Temperature

Instrument Type

Generic Name: Rotronics Temperature and Humidity Probe

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/102/

Generic Description:

Rotronics device used to measure air temperature

Sea Tech Fluorometer

Supplied Name: SeaTech Fluorometer

Supplied Description:

Sea Tech chlorophyll-a fluorometer

Instrument Type

Generic Name: Sea Tech Fluorometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/113/

Generic Description:

The Sea Tech chlorophyll-a fluorometer has internally selectable settings to adjust for different ranges of chlorophyll concentration, and is designed to measure chlorophyll-a fluorescence in situ. The instrument is stable with time and temperature and uses specially selected optical filters enabling accurate measurements of chlorophyll a. It can be deployed in moored or profiling mode. This instrument designation is used when specific make and model are not known. The Sea Tech Fluorometer was manufactured by Sea Tech, Inc. (Corvalis, OR, USA).

Sea Tech Transmissometer

Supplied Name: SeaTech Transmissometer

Supplied Description:

Sea Tech 25-cm path-length transmissometer

Instrument Type

Generic Name: Sea Tech Transmissometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0003/

Generic Description:

The Sea Tech Transmissometer can be deployed in either moored or profiling mode to estimate the concentration of suspended or particulate matter in seawater. The transmissometer measures the beam attenuation coefficient in the red spectral band (660 nm) of the laser lightsource over the instrument's path-length (e.g. 20 or 25 cm). This instrument designation is used when specific make and model are not known. The Sea Tech Transmissometer was manufactured by Sea Tech, Inc. (Corvalis, OR, USA).

Sea-Bird SBE-3 Temperature Sensor

Supplied Name: SBE-3

Supplied Description:

SBE-3 Temperature

Instrument Type

Generic Name: Sea-Bird SBE-3 Temperature Sensor

Acronym: SBE-3 Temperature

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/134/

Generic Description:

The SBE-3 is a slow response, frequency output temperature sensor manufactured by Sea-Bird Electronics, Inc. (Bellevue, Washington, USA). It has an initial accuracy of +/- 0.001 degrees Celsius with a stability of +/- 0.002 degrees Celsius per year and measures seawater temperature in the range of -5.0 to +35 degrees Celsius. more information from Sea-Bird Electronics

Sea-Bird SBE-4 Conductivity Sensor

Supplied Name: SBE-4

Supplied Description:

SBE-4 Conductivity

Instrument Type

Generic Name: Sea-Bird SBE-4 Conductivity Sensor

Acronym: SBE-4 Conductivity

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0417/

Generic Description:

The Sea-Bird SBE-4 conductivity sensor is a modular, self-contained instrument that measures conductivity from 0 to 7 Siemens/meter. The sensors (Version 2; S/N 2000 and higher) have electrically isolated power circuits and optically coupled outputs to eliminate any possibility of noise and corrosion caused by ground loops. The sensing element is a cylindrical, flow-through, borosilicate glass cell with three internal platinum electrodes. Because the outer electrodes are connected together, electric fields are confined inside the cell, making the measured resistance (and instrument calibration) independent of calibration bath size or proximity to protective cages or other objects.
