Animated map exhibiting the world's oceanic waters. A continuous body of water encircling the Earth, the world (global) ocean is divided into a number of principal areas. Five oceanic divisions are usually recognized: Pacific, Atlantic, Indian, Arctic, and Southern; the last two listed are sometimes consolidated into the first three.
Ocean acidification relates to the on-going decrease in ocean pH as a result of the uptake of anthropogenic carbon dioxide (CO2) in the ocean. Surface ocean pH is estimated to...
Navy for partnership in Indian Ocean regionLast Updated on 2010-02-06 00:00:00Chief of Naval Staff Admiral Nirmal Verma on Friday said the Navy preferred to work together with other navies in the Indian Ocean region rather than assume leadership as envisaged by the U.S.
“We are talking about coming together on a constructive level… and [Indian Navy] not coming in as a headmaster,” Admiral Verma said on the sidelines of a seminar organised as part of the multi-lateral “Milan” exercise, in which 13 countries are participating here.
He was responding to a question on how the country visualised its role following the Pentagon’s latest assessment that the Indian Navy was acquiring the capability and could possibly assume a greater security role in the region.
Nine foreign ships and delegations from 12 countries including Australia, Brunei, Bangladesh, Indonesia, Malaysia, Myanmar, New Zealand, Philippines, Singapore, Sri Lanka, Thailand and Vietnam arrived... More »

#20: First sightings of leafy seadragons!Last Updated on 2009-11-10 00:00:00I went out for another dive in search of leafy seadragons and lucked out as we spotted four throughout the dive. Two were juveniles (probably 1 - 1.5 year olds) and two were adults.

The eradication of rats on McKean IslandLast Updated on 2009-09-17 00:00:00The expedition has been going fast and furious and moments to write blog entries are sometimes fleeting. The deck salon and cabins are spaces with the constant motion of people, dive gear, science gear, NAI'A crew in their blue uniforms doing their part in running the ship, and so on. At this moment, Stuart Sandin just walked by with his wetsuit half pulled up and looking for his clipboard. Craig Cook just came to me and said he was about to set up the hyperbaric chamber again for testing; Brian Skerry walks by with two underwater camera housings with strobes, one draped over each arm like leggy spiders. All is going well as we make our way through the Phoenix Islands Protected Area (PIPA).

Assignment Blog--Brian Skerry: One Fish, Two Fish, Gray Fish, Blue FishLast Updated on 2009-09-17 00:00:00Monday September 14 - I felt like I was in the middle of a Dr. Seuss story on my third dive today at Nikumaroro. Rob Barrel, the owner of our expedition vessel NAI'A, took me to an underwater location he found that was absolutely loaded with fish! I dove late in the day, beginning around 4 p.m. and swam over some huge boulders and reef structure to get to this place where massive schools of fish swarmed. I settled down on top of a massive boulder and wrapped my legs around smaller rocks to steady myself in the swaying surge and began composing images through my viewfinder.

The visibility was not great, but it didn't need to be for the type of photos I hoped to make. The fish were not especially shy and I was able to get fairly close. I watched schools of... More »
