Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Antarctic Bottom Water Flow through the Hunter Channel* [PDF]
Journal of Physical Oceanography, 1999 The Rio Grande Rise acts as a natural barrier for the equatorward flow of Antarctic Bottom Water in the subtropical South Atlantic. In addition to the Vema Channel, the Hunter Channel cuts through this obstacle and offers a separate route for bottom-water import into the southern Brazil Basin.

Ventilation of the abyss in the Atlantic sector of the Southern Ocean
Scientific Reports, 2021 The Atlantic sector of the Southern Ocean is the world’s main production site of Antarctic Bottom Water, a water-mass that is ventilated at the ocean surface before sinking and entraining older water-masses—ultimately replenishing the abyssal global ...

Southern Ocean polynyas and dense water formation in a high-resolution, coupled Earth system model [PDF]
The Cryosphere, 2023 Antarctic coastal polynyas produce dense shelf water, a primary source of Antarctic Bottom Water that contributes to the global overturning circulation. This paper investigates Antarctic dense water formation in the high-resolution version of the Energy ...

Shoaling of abyssal ventilation in the Eastern Indian Sector of the Southern Ocean
Communications Earth & Environment, 2022 Under rapid and persistent freshening in source waters, a decline in the supply of Antarctic Bottom Water to the Australian-Antarctic Basin is compensated by an increase in ventilation of the layer immediately above, suggests an analysis of in situ ...

Interannual Variability of the Outflow of Weddell Sea Bottom Water
Geophysical Research Letters, 2020 The Weddell Sea Bottom Water (WSBW) export from 1999 to 2019 displays distinct seasonal and interannual variability. From 2014 into 2017 a marked salinity decrease was recorded, with the lowest salinity, 34.615, attained in early 2016.

Water masses in the Atlantic Ocean: characteristics and distributions [PDF]
Ocean Science, 2021 A large number of water masses are presented in the Atlantic Ocean, and knowledge of their distributions and properties is important for understanding and monitoring of a range of oceanographic phenomena.
