History of oceanic front development in the New Zealand sector of the Southern Ocean during the Cenozoic--a synthesis [PDF]
The New Zealand sector of the Southern Ocean (NZSSO) has opened about the Indian-Pacific spreading ridge throughout the Cenozoic. Today the NZSSO is characterised by broad zonal belts of antarctic (cold), subantarctic (cool), and subtropical (warm ...

Is the Atlantic Ocean driving the recent variability in South Asian dust? [PDF]
This study investigates the large-scale factors controlling interannual variability in dust aerosols over South Asia during 2001–2018. We use a parameter DA%, which refers to the frequency of days in a year when high dust activity is experienced over a ...

Occurrence and distribution of larval lanternfish (Myctophidae) from the southwest Atlantic Ocean [PDF]
This study analyzes the occurrence and distribution of lanternfish (Myctophidae) larvae along the Brazilian coast (12-22ºS) between 200 m and the surface. Three cruises were conducted during the spring/1998, winter/1999 and autumn/2000. A total of 3,394 lanternfish larvae were identified representing 27 species and Lepidophanes guentheri (Goode & Bean,

A NEW SPECIES OF GRANELEDONE (CEPHALOPODA: OCTOPODIDAE) FROM THE SOUTHWEST ATLANTIC OCEAN [PDF]
A new species of eledonid octopus is described from the southwestern Atlantic Ocean from depths between 90 and 1000 m off the coasts of southern Brazil, Uruguay, and Argentina. This species, Graneledone yamana is characterized by having a papillose skin, two well developed 'horns' above the eyes, small gills with 5-7 lamellae on the outer demibranch ...

Potential changes in the connectivity of marine protected areas driven by extreme ocean warming
Projected future climate scenarios anticipate a warmer tropical ocean and changes in surface currents that will likely influence the survival of marine organisms and the connectivity of marine protected areas (MPAs) networks.

Seismic characteristics of sediment drifts: An example from the Agulhas Plateau, southwest Indian Ocean [PDF]
Sediment drifts provide information on the palaeoceanographic development of a region. Additionally, they may represent hydrocarbon reservoirs. Because of this, sediment drift investigation has increased over the last few years. Nevertheless, a number of

Textural variations in Neogene pelagic carbonate ooze at DSDP Site 593, southern Tasman Sea, and their paleoceanographic implications [PDF]
Changes in Neogene sediment texture in pelagic carbonate-rich oozes on the Challenger Plateau, southern Tasman Sea, are used to infer changes in depositional paleocurrent velocities.

Grenadiers (Pisces, Macrouridae) of the Southwest Atlantic Ocean: biologic and fishery aspects
Several grenadier species distribute in the Southwest Atlantic Ocean. Macrourus carinatus and Caelorinchus fasciatus are more frequently identified in commercial catches and during research cruises. Those benthopelagic fishes, related to subantarctic waters, inhabit at depths beyond 200 m and in high seas, between 36° S-59° S.

First records of Neopomacentrus cyanomos (Bleeker, 1856) (Pomacentridae, Blenniiformes) in Southwestern Atlantic reefs [PDF]
Records of non‑native species in the Southwestern Atlantic reefs have increased alarmingly within the last two decades. Here, we provide the first report in the Southwest Atlantic of Neopomacentrus cyanomos (Bleeker, 1856), Regal Damselfish, a ...
