Recent changes in the surface salinity of the North Atlantic subpolar gyre [PDF]

, 2002
Sea surface salinity (SSS) was measured since 1896 along 60°N between Greenland and the North Sea and since 1993 between Iceland and Newfoundland. Along 60°N away from the shelves, and north of 53°N, the amplitude of the seasonal cycle is comparable to ...

The global geomagnetic field over the historical era: what can we learn from ship-log declinations?

Earth, Planets and Space, 2023
Modern geomagnetic field models are constructed from satellite and observatory data, while models on the millennial timescale are constructed from indirect records of thermoremanent and sedimentary origin.

A New Geomagnetic Polarity Time Scale for the Late Cretaceous and Cenozoic [PDF]

, 1992
We have constructed a magnetic polarity time scale for the Late Cretaceous and Cenozoic based on an analysis of marine magnetic profiles from the world's ocean basins. This is the first time, since Heirtzler et al. (1968) published their time scale, that

Leptons with energy >200 MeV trapped near the South Atlantic Anomaly [PDF]

Journal of Geophysical Research: Space Physics, 2003
Accurate measurements of electron and positron fluxes in the energy range 0.2–10 GeV have been performed with the Alpha Magnetic Spectrometer (AMS) at altitudes of 320–390 km in the geographic latitude interval ±51.7°. We focus on the fluxes measured in the regions nearby the South Atlantic Anomaly, defined by the local magnetic values of the magnetic ...

Remote sensing of coccolithophore blooms in selected oceanic regions using the PhytoDOAS method applied to hyper-spectral satellite data [PDF]

, 2012
In this study temporal variations of coccolithophore blooms are investigated using satellite data. Eight years (from 2003 to 2010) of data of SCIAMACHY, a hyper-spectral satellite sensor on-board ENVISAT, were processed by the PhytoDOAS method to monitor

Equatorial electrojet in the south Atlantic anomaly region

Journal of Earth System Science, 2011
Features of the equatorial electrojet are studied at Sao Luiz (2.6°S, 44.2°W, inclination −0.25°) in eastern Brazil and Sikasso (11.3°N, 5.7°W, inclination 0.1°) in the western African sector. The stations are situated on either side of the lowest magnetic field intensity in the region of rapid changes in the declination.

A dynamical framework for the origin of the diagonal South Pacific and South Atlantic convergence zones [PDF]

, 2015
The South Pacific Convergence Zone (SPCZ) and South Atlantic Convergence Zone (SACZ) are diagonal bands of precipitation that extend from the equator southeastward into the Southern Hemisphere over the western Pacific and Atlantic Oceans, respectively ...

South Atlantic anomaly campaign

Eos, Transactions American Geophysical Union, 1982
Ever since the days of the first satellite observations of the fluxes of high‐energy particles in the South Atlantic Anomaly, there has been interest in the possible atmospheric effects of the precipitating particles. Recently, Gledhill and Hoffman (J. Geophys.

Investigation on the characteristics of the South Atlantic Anomaly [PDF]

, 2021
Abstract. The South Atlantic Anomaly (SAA) is known for its weak Earth’s magnetic field strength. In this research, power spectrum analysis method was applied on the Horizontal intensity of the Earth’s magnetic field with data sample rate used at 1 min. Four active periods on 18 March 2012, 10 March 2012, 25 April 2012, and 30 June 2013 which represent
