The TANGO2 expedition ventured to accumulate new information and samples to delineate responses of marine ecosystems to shifts in ice regimes in the West Antarctic Peninsula (WAP), taking full advantage of a nimble sampling platform, the R/V Australis, a steel hulled, fully rigged motor sailor. TANGO2 took place between February and March 2024, sam...

The TANGO1 expedition ventured to accumulate new data on the responses of marine ecosystems to shifts in ice regimes in the West Antarctic Peninsula (WAP), taking full advantage of a nimble sampling platform, the R/V Australis, a steel hulled, fully rigged motor sailor. TANGO1 took place between February and March 2023, sampling two main locations...

The western Antarctic Peninsula is facing rapid environmental changes and many recent publications stress the need to gain new knowledge regarding ecosystems responses to these changes. In the framework of the Belgica 121 expedition, we tested the use of a nimble vessel with a moderate environmental footprint as an approach to tackle the urgent nee...

Animals aggregate around resource hotspots, but what makes one resource more appealing than another can be difficult to determine. In March 2020 the Antarctic fjord Charlotte Bay included >5× as many humpback whales as neighboring Wilhelmina Bay, a site previously known for super aggregations of whales and their prey, Antarctic krill. We used sucti...

This dataset relates to the biodiversity census carried out during the Belgica 121 (B121) expedition to the Western Antarctic Peninsula from February to March 2019. One of the aims of the campaign was to explore the surroundings of the Gerlache Strait and to carry out a detailed biodiversity census focusing on inter- and subtidal shallow-water area...

Report of the diving activities carried out during the Scientific Expedition Belgica 121 (www.belgica120.be) in the Gerlach Strait, Antarctic Peninsula , February-March 2019. The report has been written by the Dive Leader with review by the other dive team members, and signed by the Dive Leader, Scientific Leader and Skipper of the RV Australis.

This is the cruise report of the Belgica 121 expedition to the Gerlache Strait

Isoprene (C5H8) plays an important role in the formation of surface ozone (O3) and the secondary organic aerosol (SOA) which contributed to the climate change. This study aims to determine hourly distribution of tropospheric isoprene over the Western Coast of Antarctic Peninsula (WCAP) during the Malaysian Antarctic Scientific Expedition Cruise 201...

The Antarctic continent is known to be an unpopulated region due to its extreme weather and climate conditions. However, the air quality over this continent can be affected by long-lived anthropogenic pollutants from the mainland. The Argentinian region of Ushuaia is often the main source area of accumulated hazardous gases over the Antarctic Penin...

Isoprene (C5H8 ) plays an important role in the formation of Secondary Organic Aerosol (SOA) and surface ozone (O 3 ) in the troposphere. In Polar region, its oxidation products in the photochemical reaction will lead to the surface warming of the water and ice surface. This study aims to measure of isoprene mixing ratios and investigate the possib...

Here we report a sighting of a large school of fin whales on 30th May 2010 approximately 2,810 km west of the continental coast of Chile (21°27'S, 97°34'W). This sighting supports the limited available information that fin whales migrate to Sub-tropical open ocean waters during the austral autumn-winter. Given the accepted migration pattern of fin...
