Hi Tweets,

In view of the big Sabine's Gull year in Cascadia, here's some interesting
remarks from UKbirdnet.

> Hi.
>
> Tony A.J. Morris comments upon the issue of climate change and the
> possibility of the Gulf Stream shifting away from Britain and Ireland.
>
> In connection with the Kyoto meeting, this has been a subject in
> Norwegian news for the last days as well. It may not be of direct
> interest to birders, but it surely must be of indirect concern.
>
> Last nights news did, however, calm things down a bit, as says one
> member of a European expert panel: The problem so far is the
> significant reduction in the production of cold deep sea water going
> SW from the polar current coming down east of Greenland. This has far
> reaching consequences as a pump for other currents, partly also the
> warm Gulf Stream. But this change has already happened, and the Gulf
> Stream (which experts in fact says has a misleading name) still flows.
> According to these experts, there is no immediate concern that the
> Gulf Stream will change. The reduced production of cold, deepwater is
> reckoned to be part of a natural phenomena.
>
> And for those of you stayers who still is reading this piece of text,
> I have the following question and seabird related thoughts:
>
> 1. Does anyone know of any seabird study that is relating things to
> the shifting ocean currents.
>
> 2. This autumn saw one of historys most spectacular influxes of
> pelagic seabirds, notably Sooty Shearwaters and Sabines Gulls, but
> also many others. My "hypothesis" is that these occurrences were not
> only related to strong winds, but maybe as much to the distribution of
> the items they feed upon. The distribution of food along the sea
> surface may be a direct result of ocean temperature and prevailing
> currents.
>
> Maybe seabirders have already "documented" the things that
> oceanographers are looking for?
>
> Any comment is welcomed.
