Title: AMLR Acoustics Data 1996-2011 v1.1
Short Name: AMLR Acoustics Data 1996-2011 v1.1
Status: Completed
Creation Date: 1996
Abstract:

Calibrated, integrated, and averaged acoustics data, including estimates of krill (Euphausia superba) biomass density, collected around Elephant Island, the South Shetland Islands, and the Antarctic Peninsula by the U.S. AMLR Program. Data are integrated over depths from about 10-15m down to the bottom or 250m (whichever is shallower) and averaged over 1-nmi intervals.

Purpose:

Scientific acoustic data used toe estimate the biomass of Antarctic krill.

Other Citation Details:

The datasets incorporated into this archive have been collected by researchers affiliated with the U.S. Antarctic Marine Living Resources (AMLR) Program under the National Marine Fisheries Service (NMFS). These data are part of a long term ecosystem project centered on the South Shetland Islands off the Antarctic Peninsula, Antarctica. Funding for this project was from the NMFS AMLR Program. Data were collected from ship based platforms.

Instruments

Instrument 1

CC ID: 863149
Identifier: Simrad EK500
Docucomp UUID: fef1c011-226e-4dd3-97a2-aae7afe86409
Instrument / Gear: Instrument
Instrument Type: Singlebeam Echosounder
Description:

The EK500 is a triple frequency scientific echo sounder with a range of available single frequency transducers. This echo sounder was widely used by NOAA Marine fisheries researchers until its replacement by the Simrad EK60 echo sounder

Instrument 2

CC ID: 863150
Identifier: Simrad EK60
Docucomp UUID: b7ae3f00-701c-11e0-a1f0-0800200c9a66
Instrument / Gear: Instrument
Instrument Type: Singlebeam Echosounder
Description:

The Simrad EK60 Scientific Sounder system is a new generation fishery researchtool, based on experience from the EK500. The new electronic hardware is combined with up to date PC processing and Windows operation. The EK60 provides facilities for accurate echo sounding, data storage, data analysis and reporting results. The system communication is through Ethernet, which gives flexibility in the location of the EK60 system units and allows easy access to data from other instruments or stations on a vessel network. A post processing software, BI60, is also included in the EK60 system.
