As you can see in the map above, the most heavily oiled shoreline still corresponds with the most dead whales and dolphins. Bottlenose dolphins are shown as circles and other species as squares. Premature, stillborn, or neonatal bottlenose dolphins (with actual or estimated lengths of less than 115 cm/45 inches) are shown as a circle with a black dot inside. Pink points mark the most recent week of data. Green points mark are all other cases since January 1.

Here you can see how the numbers of strandings have not yet stabilized or even begun to decline. In some cases they’re still growing. The magenta-colored bars mark strandings per month in the year 2010. The ivory-colored bars mark strandings per month so far this year.

In my Mother Jones article “The BP Cover-Uplast year, I wrote about the kind of long-term problems the Gulf might face not just from oil but from extreme quantities of oil in very deep water, as well as from chemical dispersant, including dispersant injected into very deep water.

Sadly, it seems that cetaceans—past, present, and future—may be bearing some of those burdens.
