Quantification of Antarctic Bottom Water Pathways in the Australian‐Antarctic Basin

Journal of Geophysical Research: Oceans
AbstractAntarctic Bottom Water (AABW) formation drives the lower limb of the meridional overturning circulation, influencing the Earth's climate, carbon cycle, and marine biological productivity. Recent findings suggest that AABW across the Southern Ocean is changing, including freshening, warming and thinning.

Mapping Escolar (Lepidocybium flavobrunneum) in Motion: Oceanographic Forces Shaping Its Habitat in the Southwestern South Atlantic, With Insights From Fishers' Perceptions

Fisheries Oceanography, EarlyView.
ABSTRACT Lepidocybium flavobrunneum [Smith, 1843], commonly known as escolar, is a large pelagic species, important for global and local fisheries, particularly in the southwestern South Atlantic Ocean (SWAO), where it constitutes a significant portion of the catch.

Validation of a global finite element sea ice-ocean model [PDF]

, 2009
Results from a global Finite Element Sea iceOcean Model (FESOM) are evaluated using a wide range of observational datasets. FESOMs ocean component is a primitive-equation, hydrostatic ocean model using isopycnic diffusion and a Gent-McWilliams scheme to ...

Antarctic Bottom Water Flux in the Equatorial Western Atlantic*

Journal of Physical Oceanography, 1997
A moored array at the equator in the western basin of the Atlantic provides a 604-day time series of abyssal currents and temperatures spanning the full breadth of the Antarctic Bottom Water (AABW) flowing from the Brazil Basin to the Guiana Basin. Mean AABW transport is estimated to be 2.0 Sv (Sv [ 106 m3 s21), comprising organized westward flow of 2 ...

Contrasting life‐history strategies of three sympatric icefish species in the northern Scotia Sea

Journal of Fish Biology, EarlyView.
Abstract Comprehending a species' life‐history strategies is crucial to inform effective conservation efforts. Commercial fishing impacts icefish (family: Channichthyidae) in the Scotia Sea, but detailed information on species‐specific life histories remains largely unknown.

Unilateral Action on Climate Change and the Moral Obligation to Take Leadership

Journal of Social Philosophy, EarlyView.
ABSTRACT We claim that a moral obligation to take climate leadership by means of unilateral mitigation depends on the existence of a plausible follow‐the‐leader mechanism whereby unilateral mitigation by some increases the probability of sufficient mitigation by others to avert catastrophic climate impacts.

The age and origin of the central Scotia Sea [PDF]

, 2010
Opening of the Drake Passage gateway between the Pacific and Atlantic oceans has been linked in various ways to Cenozoic climate changes. From the oceanic floor of Drake Passage, the largest of the remaining uncertainties in understanding this opening is

Enzymatic strategies for phosphorus utilization in periphyton: A study of alkaline phosphatase kinetics in post‐mining lakes

Journal of Phycology, EarlyView.
Abstract Alkaline phosphatase (AP) plays an important role in phosphorus (P) cycling in aquatic ecosystems, particularly under nutrient limitation. In post‐mining lakes of Czechia, periphyton forms extensive mats despite chronic P deficiency, suggesting dissolved organic P (DOP) may serve as a key P source.
