Greetings, With the current need for alternative energy sources, we are starting to assess a number of pilot projects dealing with hydrokinetic/tidal energy. These projects involve either buried or free submarine cables and I am finding there's a dearth of information regarding marine mammal interactions with cable systems, e.g. entanglements, or potential effects of electromagnetic fields. I do have a document by Norman and Lopez (2002) and various articles on wind farm issues, but was wondering if anyone is aware of further information. I have accessed the various databases in NOAA's Seattle library, and, of course,Google Scholar without much success. If anyone can recommend other specific sources to check, that would be great as well. Thank you, Kate Savage katharine.savage@noaa.gov -- Katharine Savage, Marine Mammal Specialist Protected Resources Division NOAA Fisheries, Alaska Region Ph: 907-586-7312 Fax: 907-586-7012
