Temporal variability in call rates of Weddell (leoptonychotes weddellii) and Leopard (Hydrurga leptonyx) seals near Davis station, East Antarctica Marine Mammal Science, 2025 (Ref: 17471)
Authors:
Simmonds E.A.Terhune J.M.Miller B.S.van den Hoff J.
Category 1: Peer-reviewed literature

We investigated Weddell seal (Leptonychotes weddellii) and leopard seal (Hydrurga leptonyx) vocalizations using passive acoustic monitoring beneath landfast ice and open water, 5.6?km seaward from Davis Station, East Antarctica. Eight-minute recordings were manually sampled at 1?h intervals over 24?

Both net sea ice extent (SIE) and area (SIA) were close to the 1981–2010 average for January through August 2016, after which there was a dramatic departure from the mean through to the end of the year (Fig. 6.8a). Maximum net SIE peaked on 31 August (18.44 × 106 km2)…

We present here data of mineral dust variability retrieved from an ice core of the central West Antarctic, spanning the last five decades. Main evidence provided by the geochemical analysis is that northerly air mass incursions to the coring site, tracked by insoluble dust microparticles…

A new method for identifying the Pacific-South American pattern and its influence on regional climate variability Journal of Climate, 2016 (Ref: 15914)
Authors:
Irving D.Simmonds I.
Category 1: Peer-reviewed literature

The Pacific-South American (PSA) pattern is an important mode of climate variability in the mid-to-high southern latitudes. It is widely recognized as the primary mechanism by … which the El Nino-Southern Oscillation (ENSO) influences the south-east Pacific and … south-west Atlantic…
