Antarctic krill (Euphausia superba) is the central prey species in the Southern Ocean food web, supporting the largest and fastest-growing fishery in the region, managed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).
The passive sinking flux of particles, termed the biological gravitational pump (BGP), is an important component of the ocean's biological carbon pump. In addition, carbon-rich particles are actively injected to depth through the diel vertical migration (DVM)…
The capacity sharing approach of the Scientific Committee on Oceanic Research (SCOR) focuses on supporting opportunities for individual ocean scientists and students within SCOR's portfolio of scientific activities and through targeted capacity development opportunities (Morrison et al.…
The Galactic cosmic ray spectrum manifests pronounced variations over the 11-year sunspot cycle and more subtle variations over the 22-year solar magnetic cycle.
Antarctic climate warming and atmospheric CO2 rise during the last deglaciation may be attributed in part to sea ice reduction in the Southern Ocean. Yet, glacial–interglacial Antarctic sea ice dynamics and underlying mechanisms are poorly constrained, as robust sea ice proxy evidence is sparse.
This Summary for Policymakers uses information and infographics from the research articles, updated with other more recent research articles, to provide the following information: 1.
Species distributions are predicted to change with future climate-associated ecosystem changes such that so-called 'vagrant' individuals may become established or re-establish in areas currently thought to be beyond their principle ranges.
As we learn more about the importance of cetaceans in the Antarctic, including their populations' recovery and needs as krill and fish predators, it is increasingly clear that cetacean science is vital for informing ecosystem-based management.
No detailed report on marine mammals has been published … previously from the Australasian Antarctic Expedition of 1911 –14 … (AAE)or the British,Australian and New Zealand Antarctic Research Expedition of 1929 –31 (BANZARE).
Decadal variations of the quasi-stationary wave amplitude and zonal structure are analyzed using the TOMS data. Seasonal dependence of total ozone content (TOC) is considered.
1. Subordinate helpers in cooperative societies may gain both immediate and future benefits, including paternity and territorial inheritance. However, if such opportunities correlate with rank … in the queue, it is unclear why such queues should be stable. 2.
This reference document provides information on physical and biological data layers that … have been collated in advance of the 2007 CCAMLR Workshop on Bioregionalisation. This is … not an exhaustive list, as additional data may be made available by participants during the … workshop itself.
