Ocean bathymetry plays an instrumental role in stirring ocean circulation and ocean mixing, shaping the transport of ocean heat, freshwater, oxygen, and carbon, influencing the propagation of tides and tsunamis, and controlling the dispersion of sediments, nutrients, and planktonic species.
Ocean alkalinity enhancement is a potential strategy for gigatonne-scale atmospheric carbon dioxide removal. It uses alkaline substances to convert seawater carbon dioxide into (bi)carbonate, enabling uptake of additional carbon dioxide from the atmosphere.
The use of molecular assays to assess the presence of species using environmental DNA (eDNA) and RNA (eRNA) as analytes has diversified as the field of environmental surveillance advances. These methods can be used, for example…
The use of environmental DNA (eDNA) and RNA (eRNA) methods is a rapidly advancing field that provides fast, cost-effective, non-invasive methods to identify the presence of target species. These methods can be used, for example…
The fin whale is listed as globally vulnerable, with ongoing threats to their population, yet little is known about the distribution and movements of the Southern Hemisphere sub-species, Balaenoptera physalus quoyi.
This study presents evidence of diel patterns in fin whale (Balaenoptera physalus) 20 Hz acoustic presence in Eastern Antarctic waters. Passive acoustic recordings were collected at four sites in Eastern Antarctica from 2013 to 2019.
Abstract: Two sediment cores collected from beneath the Amery Ice Shelf, East Antarctica describe the … physical sedimentation patterns beneath an existing major embayed ice shelf. Core AM01b was collected … from a site of basal freezing, contrasting with core AM02…
Species of the genus Pyramimonas (Prasinophyceae) are a common, widespread, but minor component of the Antarctic marine phytoplankton. They are … often associated with the seasonal sea-ice environment. Pyramimonas gelidicola … (McFadden, Moestrup & Wetherbee, 1982)…
In their Policy Forum review “Do the largest protected areas conserve whales or whalers?” (Science, 28 Jan 2006, p.525), Gerber and co-authors criticised the scientific basis of the International Whaling Commissions’ (IWC)…
The MarClim project was a four year multi-partner funded project created to investigate the effects of climatic warming on marine biodiversity. In particular the project aimed to use intertidal species, whose abundances had been shown to fluctuate with changes in climatic conditions…
Electromagnetic ion cyclotron (EMIC) waves are generated in the equatorial … region of the plasmasphere-magnetospherbey internal wave-particle interaction … with ring current ions. In ground observations they are observed as Pc 1-2 (0.1-5 … Hz) waves…
Past and recent dissolved iron (dFe) and total dissolvable iron (TDFe) datasets from the Atlantic Meridional Transect (AMT) program are presented.
A solar occultation sensor, the Improved Limb Atmospheric Spectrometer (ILAS)-II, measured 5890 vertical profiles of ozone concentrations in the stratosphere and lower … mesosphere and of other species from January to October 2003. The measurement latitude … coverage was 54–71°N and 64–88°S…
ABSTRACT. We present highly resolved, annually dated, calibrated proxies for atmospheric circulation … from several Antarctic ice cores (ITASE (International Trans-Antarctic Scientific Expedition), Siple … Dome, Law Dome)…
