Scientific sampling event log from R/V Oceanus OC476-01 from the Nova Scotian continental slope waters; Cape Hatteras margin slope waters (Carbon Export project)

Expand/Collapse All

Description

This scientific sampling event log was created during the cruise using an early implementation of the Rolling Deck to Repository (R2R) event log application (ELOG with cruise-specific custom configuration files). It is a record of all scientific sampling events completed during the cruise. The event ID numbers are derived from UTC as YYYYMMDD.hhmm and are unique within the cruise.

Data Processing Description

ISO_DateTime_UTC was added by BCO-DMO.

Instruments

Global Positioning System Receiver

Supplied Name: GPS

Supplied Description:

The R2R event logger system records lat/lon/time directly from the vessel navigation system via the ship's local network.

Instrument Type

Generic Name: Global Positioning System Receiver

Acronym: GPS

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/POS03/

Generic Description:

The Global Positioning System (GPS) is a U.S. space-based radionavigation system that provides reliable positioning, navigation, and timing services to civilian users on a continuous worldwide basis. The U.S. Air Force develops, maintains, and operates the space and control segments of the NAVSTAR GPS transmitter system. Ships use a variety of receivers (e.g. Trimble and Ashtech) to interpret the GPS signal and determine accurate latitude and longitude.

Parameters

Date and time formats are described in python strftime() syntax.
