Description

This dataset contains site information for R/V Centennial trawl surveys in the Hood Canal, WA from 2012-2013.

Methods & Sampling

Samples sites were chosen to include southern reaches (Union, Hoodsport) where low dissolved oxygen was common and paired sites to each (Dabob, Duckabush) that shared similar bathymetric profiles but are less prone to low dissolved oxygen.

Data Processing Description

BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* Added lat lons in decimal degree format
* added space between degree and "deg" in SW_lat to be consistent with the rest of the dataset.

Midwater Trawl

Supplied Name: Marinovich midwater trawl

Supplied Description:

Instrument Type

Generic Name: Midwater Trawl

Acronym: TrawlMid

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/23/

Generic Description:

A mid-water or pelagic trawl is a net towed at a chosen depth in the water column to catch schooling fish such as herring and mackerel. Midwater trawl nets have very large front openings to herd schooling fish toward the back end where they become trapped in the narrow "broiler". The sides of the deployed net are spread horizontally with two large metal foils, called "doors," positioned in front of the net. As the trawler moves forward, the doors, and therefore the net, are forced outward, keeping the net open.
This instrument designation is used when specific make and model are not known.

Water Depth Logger

Supplied Name: Kongsberg Marine P150 net monitor

Supplied Description:

Trawl depth measured using Kongsberg Marine P150 net monitor.

Instrument Type

Generic Name: Water Depth Logger

Generic Description:

For measuring and recording water levels in rivers, streams, and wells.

Parameters
