This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

Even a Slow Cargo Vessel Can be Fatal
A study, in the journal Marine Mammal Science, has found that endangered North Atlantic Right Whales have an 80% chance of being killed in a collision with a large cargo vessel travelling at only 10 knots (https://www.theguardian.com/environment/2020/dec/24/even-slow-moving-boats-likely-to-kill-endangered-right-whales-in-a-collision-study-finds). This is quite slow for shipping and reflects a 'speed limit' put in place by the Canadian government, in an attempt to reduce cetacean deaths. The data suggests that a) the 'speed limit' will have to be reduced or b) some other means found to prevent shipping and the whales coming into contact.
