Statement

Methodology:

The data were collected across the Scotia Sea during austral autumn 2004 (JR100), spring 2006 (JR161), summer 2007/08 (JR177) and autumn 2009 (JR200) as part of BAS' Ecosystems Discovery 2010 project. The mesopelagic fish samples were collected with a RMT25 net deployed repeatedly between 0-1000 m at nominal sampling stations between the Antarctic Polar Front and the South Orkney Islands. Net deployments were performed during day and night on all surveys except JR200, where sampling was confined to the night. During each survey, stomachs from sub-samples of the biomass-dominant mesopelagic fish species were frozen at -20 degrees C for subsequent microscopic analysis back at the laboratory. Fish were sexed and staged where possible. This analysis involved the identification and quantification of the stomach's contents by microscopy. Where possible, prey items were identified to the lowest taxonomic level, typically species or genus level, and then enumerated and weighed to the nearest 0.01 g. Details on the survey sampling programmes are in the JR100, JR161, JR177 and JR200 cruise reports. An overview of the surveys, methods and results to date are also given in the publications below.

Data were collected at the following approximate depth zones:

1: 0-200 m

2: 200-400 m

3: 400-700 m

4: 700-1000 m

During a haul, a net was open for approximately 20-60 minutes in each depth zone. The net was towed obliquely at ~2.5 knots during this time.

Data collection:

1. An RMT25 trawl (25 m2 mouth diameter, 5 mm minimum mesh size)

2. Motion compensated weighing scales

3. Binocular microscope

4. Calibrated laboratory weighing scales

5. Volumetric flasks

Data were collected using an RMT25 trawl net as described in the publication and the SeaVoX Device Catalogue link below:

Data quality:

Data have been checked for typographic errors and obvious outliers and were corrected on a few instances according to the original laboratory analysis records. The data are accurate and of a high quality within the confines of conventional stomach contents analysis techniques.
