Check out the video in today's expedition update from Oceana marine scientist Elizabeth Wilson. The scientists can't resist giving the baby bonnethead sharks a few smooches before releasing them.

The Oceana Latitude is now docked in St. Petersburg, FL for the next few days. I’ve re-boarded the Latitude with two scientists from the National Aquarium, Andy Dehart and Andrew Pulver. We’ll be using two of the Latitude’s tenders (smaller boats), the Longitude and the Lat-long, to do shark research day trips.

It’s time for the next leg of the journey: shark tagging! Dustin reports:

The Oceana Latitude is now headed South, down the west coast of Florida.

While the ship is docked in St. Petersburg for the next few days, scientists from Oceana and the National Aquarium, including Discovery Channel shark advisor Andy Dehart, will work to tag various shark species several miles offshore.

In addition to collecting basic data from each shark, the attached metal tags can provide future information on stock identity, movements and migration, abundance, age and growth, mortality, and behavior. The tags can also help identify these sharks later as those that were in the general vicinity of the Deepwater Horizon oil disaster, which could help to determine the long-term impacts of the oil spill on shark populations.

Oceana hopes to see several shark species, including spinner, blacktip, blacknose, dusky, lemon, bull, mako, tiger, hammerhead and bonnethead.
