Polar marine invertebrates serve as bellwethers for species vulnerabilities in the face of changing climate at high latitudes of the Earth. Ocean acidification, warming/heatwaves, freshening, sea ice … retreat and productivity change are challenges for polar species.
Antarctic and Southern Ocean science is vital to understanding natural variability, the processes that govern global change and the role of humans in the Earth and climate system. The potential for new knowledge to be gained from future Antarctic science is substantial. Therefore…
Introduction: This document updates the research bibliography of SC/66b/SAN01 presented in 2016. The Southern Ocean Sanctuary (SOS) was established by the Commission in 1994. The area covered by the SOS in combination with the complementary Indian Ocean Sanctuary (IOS) is shown in Figure 1.
Antarctic minke whales (Balaenoptera bonaerensis, AMW) are an abundant, ice-dependent species susceptible to rapid climatic changes occurring in parts of the Antarctic. Here, we used remote biopsy samples and estimates of length derived from unoccupied aircraft system (UAS)…
Catch per unit effort (CPUE) is often the only data available from historical fisheries for inferring distribution and abundance of exploited populations. CPUE underestimates variations in relative abundance when gross effort data are only measured in total operating days.
The method traditionally used to estimate pack-ice seal abundance employs sighting surveys from ships or aircraft to … estimate the number of seals hauled out on the ice, combined with studies of haul-out behaviour to estimate the proportion … of time spent on the ice.
1. The crabeater seal … Lobodon carcinophaga … is considered to be a key species in the krill-based foodweb … of the Southern Ocean. Reliable estimates of the abundance of this species are necessary to … allow the development of multispecies, predator…
Chlorophyll fluorescence was used to measure changes in the maximum fluorescence yield (F0m) and effective quantum yield (F/F0m ) of Antarctic macroalgae in response to dissolved copper.
The Doppler velocity and spectral width are two … important parameters derived from coherent scatter radar … systems. The Super Dual Auroral Radar Network (Super- … DARN)…
We use line transect detection functions together with generalized linear and additive … models to estimate detection probability when detection on the line ("g(O)") may … not be certain.
