Plankton, a diverse group of aquatic organisms, make Earth livable, regulate aquatic life, and provide benefits to human societies such as access to clean water, food security, and well-being. They also support economies and inspire biotechnological innovations.
A southern right whale (Eubalaena australis) was found dead, stranded on a remote rock platform at Torndirrup, Western Australia, on 20 September 2022.
Large earthquakes in the vicinity of Antarctica have the potential to cause postseismic viscoelastic deformation affecting measurements of displacement that are used to constrain models of glacial isostatic adjustment (GIA). In November 2013, a Mw 7.
As the use of coastal and offshore environments expands, there is a need to better understand the exposure of marine megafauna to anthropogenic activities that potentially threaten their populations. Individual satellite telemetry studies are often hampered by small sample sizes…
During the summer of 2008/09, measurements were taken at 34 magnetotelluric (MT) stations along profiles totaling approximately 180 line km in the Prydz Bay region of Antarctica. Prydz Bay comprises several regions of coastal outcrops with distinct geological histories…
We compiled and reviewed 248 cases of reported vessel collisions with small cetaceans worldwide and with large … cetaceans in the Southern Hemisphere. Difficulties were encountered with the comparison of highly variable data in … terms of quality (evidence), sources…
The application of blue-dye to fishing baits is a seabird bycatch mitigation technique used … in some pelagic longline fisheries that is thought to make the baits less visible and hence … less attractive to seabirds. We tested this assumption in two ways. First…
ABSTRACT: Collisions with vessels are a well-documented conservation problem for some populations of large whales (LW) in the Northern Hemisphere. Less attention has been given to incidents in the Southern Hemisphere or to small cetaceans … (SC) worldwide…
Blue-dyed bait is a seabird bycatch mitigation technique which is assumed to reduce the … contrast between the bait and the ocean background making baits visually cryptic to seabirds. We tested this assumption in two ways. First, using measured spectral profiles of blue-dyed … baits (fish and squid)…
Common geological, geochemical, and geophysical characteristics of continental fragments of East … Gondwana and adjacent oceanic lithosphere define a long-lived, low-volume, diffuse alkaline magmatic … province (DAMP) encompassing the easternmost part of the Indo-Australian Plate, West Antarctica…
The Adare Trough, located 100 km NE of Cape Adare, Antarctica, is the extinct third arm of a Tertiary spreading ridge that … separated East from West Antarctica. We use seismic reflection data, tied to DSDP Site 274…
Antarctica’s Lambert graben, Australia’s North West Shelf, and the eastern Indian Peninsula all host thick, fault-bounded … Permian-Triassic successions. These terranes were adjacent to each … other in Gondwana. The Lambert graben intersects the modern … coastline…
Macquarie Island, located along the Australian-Pacific transform plate boundary~1200 km south of New Zealand, consists of uplifted oceanic crust that still lies within the ocean basin where it formed. A lower crustal and upper mantle section of sheeted dikes…
Macquarie Island is an exposure above sea-level of part of the crest of the Macquarie Ridge. The ridge marks the Australia-Pacific plate boundary south of New Zealand…
