Carry-over effects relate to events or processes that influence individual performance in a subsequent season, but their occurrence in the annual cycle of migratory avian taxa is seldom studied. We […]
When conducting marine seismic surveys, ocean currents noticeably perturb seismic streamers from their desired location. To accurately monitor a reservoir, the receivers in the streamers must be as close as […]
The Oceania population of humpback whales, comprising sub-stocks E2, E3, and F, was heavily depleted by whaling operations in the 20th century and is now classed as Endangered by the […]
Humpback sub-stocks BSE1 (East Australia), BSE2 (New Caledonia), BSE3 (Tonga) and BSF2 (French Polynesia) show significant genetic differentiation, yet share common high latitude feeding grounds between 130E-100W and were subject […]
Regional populations of bottlenose dolphins (Tursiops truncatus) around New Zealand are genetically isolated from each other and the species was recently classified as nationally endangered based on relatively small population […]
This paper presents mesospheric carbon monoxide (CO) data acquired by the ground-based microwave radiometer of the British Antarctic Survey (BAS radiometer) stationed at Troll station in Antarctica (72° S, 2.5° […]
The results of the first 18 months of the PLASMON project are presented. We have extended our three, existing ground-based measuring networks, AWDANet (VLF/whistlers), EMMA/SANSA (ULF/FLRs), and AARDDVARK (VLF/perturbations on […]
Despite considerable research on biological invasions, key areas remain poorly explored, especially ways to reduce unintentional propagule transfer. The Antarctic represents a microcosm of the situation, with the numbers of […]
This study provides a mechanistic explanation of why the Holton-Tan (HT) effect, a phenomenon in which the strength of northern stratospheric winter polar vortex synchronizes with the equatorial quasi-biennial oscillation […]
HCHO was monitored throughout the year 2009 at the coastal East Antarctic site of Dumont d’Urville (DDU) using Aerolaser AL-4021 analyzers. The accurate determination of less than 100 pptv required […]
