Biological samples collected using a vertical Bongo net and Van Veen grab during ANTARXXXI Leg 1 cruise (2024–2025)
Listed in GBIF
This dataset documents marine biological samples collected during ANTAR XXXI Leg 1, the first leg of the 31st Peruvian Scientific Expedition to Antarctica.
Description
The cruise was conducted aboard the BAP Carrasco from 3 December 2024 to 7 January 2025 in the Bransfield Strait and around the South Shetland Islands. Biological material from the water column was collected at 24 stations using a double-ring vertical Bongo net equipped with 100 µm and 200 µm mesh nets and a mechanical flow meter.
The net was typically deployed to a depth of 200 m, or to 20 m above the seabed at shallower stations, and towed vertically at 30 m/min. In rougher conditions, with winds exceeding 10 knots, the deployment speed was reduced to 20 m/min. Each collected sample was divided into two portions: one was examined onboard and subsequently preserved in 96% ethanol, while the other was preserved immediately in 96% ethanol.

Benthic biological material was collected opportunistically from sediment retrieved using a Van Veen grab. The grab was deployed at eight stations, four of which yielded successful samples. After retrieval, the sediment was processed onboard either by sieving and washing with seawater or by transferring it to a tissue bag, rinsing it thoroughly with seawater and sorting the retained biological material in the wet laboratory.
The dataset includes sampling-event and occurrence records with associated dates, geographic positions, depths, sampling methods and preliminary taxonomic identifications. The collected material supports subsequent taxonomic identification, imaging, genetic research and analyses of Antarctic marine biodiversity. This dataset is published as open data with technical support provided by SCAR Antarctic Biodiversity Portal (biodiversity.aq) (BELSPO project RT/23/ADVANCE).
