Geomagnetic observations on Tristan da Cunha, South Atlantic Ocean
Annals of Geophysics, 2009 Few geomagnetic ground observations exist of the Earth’s strongest core field anomaly, the South Atlantic Anomaly<br />(SAA). The geomagnetic repeat station on the island Tristan da Cunha, located half-way between South Africa<br />and South ...

Asymmetry in the effect of North Atlantic sea surface temperature on the eddy‐driven jet
Quarterly Journal of the Royal Meteorological Society, EarlyView.Projections of climate over Europe and the Atlantic are uncertain due to the uncertainty surrounding future changes in North Atlantic sea surface temperatures (SSTs). Here, we demonstrate that warming in the North Atlantic Ocean is linked to a transition to a negative phase of the North Atlantic Oscillation, as well as to an equatorward displacement of

South Atlantic island record reveals a South Atlantic response to the 8.2 kyr event [PDF]
Climate of the Past, 2008 One of the most distinct climate fluctuations during the Holocene is the short and rapid event centred around 8200 years ago, the 8.2 kyr event, which was most likely triggered by glacial melt-water forcing from the receding Laurentide ice-sheet ...

Sustainable Development, EarlyView.ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

State Choices, Unequal Access: Policies Shaping Reproductive Health Care Across the United States
The Milbank Quarterly, EarlyView.Policy Points State policies and programs play an outsized role in shaping availability and access to sexual and reproductive health services across the nation. This has a major impact on women's access to contraception, abortion, and maternity services.

Integrative Zoology, EarlyView.We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Estimating the total mortality of seabirds following a marine heat wave
Conservation Biology, EarlyView.Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

Long-term persistency of a strong non-dipole field in the South Atlantic
Nature CommunicationsEarth’s magnetic field exhibits a dominant dipole morphology. Notwithstanding, significant deviations from the dipole are evident today, particularly the South Atlantic Anomaly (SAA), characterized by anomalously low-field intensity and high directional ...
