Descrição
NIWA was contracted by the New Zealand Government, through its agent Land Information New Zealand (LINZ), to conduct a 51-day scientific study of areas in the Eastern & Central Ross Sea and around Scott & Balleny Islands, Antarctica. This work included biodiversity studies for the Ministry of Fishes (MFish), and marine mammal and sea bird studies for MFish and Department of Conservation (DoC).

| Descrição do Design | The MFish survey plan was two fold. First was the collection of underway data during transits and while the geophysical survey was progressing. These data included towing a continuous plankton recorder during transits, continual surface fluorescence measurements, water temperature and salinity measurements, recording data from the 120khz echo sounder, sea bird and mammal observations. The second part of the MFish plan was to collect data under the Ocean Survey 2020 priority plan. These proposals were then prioritised as follows: (1) Biodiversity Study for MFish: Continental shelf break (mid priority); Eastern approaches to Balleny Islands (high); Balleny Islands (high); and the Seamount between Scott and Balleny Islands (low). (2) DOC: Marine mammals and bird observations (high). |

Métodos de Amostragem
During daylight hours hourly counts of seabird abundances and continuous recording of marine mammal sightings with occasional directed in situ sampling using epibenthic sleds, still and video cameras and krill nets

Descrição dos passos do método:
- Instantaneous counts of birds at 3 distances and bird transect counts
- Marine mammal transect counts
- Camera stations (still and video) were used to test the feasibility of obtaining relative abundance estimates and local density estimates of demersal fishes by comparing fish abundances, size frequencies and species compositions in still camera images during periods of continuous lighting vs. occasional strobe lighting during benthic camera transects when the camera system was actively “flown” 5-10 m above the bottom while the Tangaroa was slowly drifting or underway (~0.5 knot). A colour video camera recorded fish behaviour during the flood-lit phase and verified the period that the flood light was on. The work was planned to take place at randomly positioned stations in one depth stratum < 1000m of one area of higher demersal fish abundance identified from existing catch rate data.
- Meso-zooplankton (2x2m fine-mesh (2mm)) net was used to opportunistically sample midwater andcsurface swarms of krill and other mesopelagic species.
- Epibenthic sled (mouth opening 1.4 x 0.5 m, 2 m long, 25 mm mesh diameter) was used to sample the uppermost infaunal and the epifaunal components of the benthic communities. The epibenthic sled was towed at a speed of 1.5 knots for a distance of ~0.5 nm parallel to the depth contour yielding paired sled and photographic estimates of benthic macro-invertebrate abundance and composition suitable for tests of association with demersal fish abundance and community composition.
