Dear Colleagues, We are glad to announce a new publication, where we demonstrated that gas bubbles in bycaught marine mammals arise from supersatured tissues. This is new evidence of nitrogen accumulation in the tissues of freely diving marine mammals. Our results also show the importance of sampling gas bubbles from the coronary veins or thoracic regions since these seemed to be the last locations in being affected by putrefaction.

We also would like to take this chance to inform you that gas analyses can be run at Woods Hole Oceanographic Institution, MA, USA, or at the University of Las Palmas de Gran Canaria, Canary Islands, Spain. You can find a step-by-step protocol and a data collection sheet in the following link: http://www.whoi.edu/hpb/viewPage.do?id=129756 Please let us know if you have any further questions.
