Table 2.3-1. IPY<br />

projects in the<br />

Southern Ocean. The<br />

projects are grouped<br />

by the primary<br />

theme to which<br />

they contribute, but<br />

many of the projects<br />

spanned disciplines<br />

and themes.<br />

IPY 20 07–20 08<br />

Here, we summarize the rationale, field programs<br />

and early scientific highlights from IPY programs in<br />

the Southern Ocean to show that the IPY has provided<br />

significant advances in our understanding of the<br />

Southern Ocean.<br />

Southern Ocean Research During IPY<br />

IPY activities in the Southern Ocean spanned<br />

a vast range of phenomena, in many disciplines.<br />

Some projects focused on the role of the Southern<br />

Ocean in the Earth system, through its influence on<br />

global climate and the carbon cycle; some projects<br />

focused on understanding the processes that control<br />

the biophysical and ecological systems, and their<br />

interactions; others were concerned with past or<br />

future change in the Southern Ocean system. For<br />

the purpose of this overview, it is useful to group IPY<br />

activities into four themes along broadly disciplinary<br />

lines, although most IPY projects had a strong<br />

interdisciplinary flavour:<br />

1. Ocean circulation and climate<br />

2. Biogeochemistry<br />

3. Marine biology, ecology and biodiversity<br />

4. Antarctic sea ice<br />

We discuss the overall objectives, achievements<br />

and scientific highlights in each of these themes, with<br />

a focus on the larger projects of circumpolar scale. A<br />

total of 18 IPY projects with a Southern Ocean focus<br />

were endorsed (Table 2.3-1).<br />
