Diving into Naked Oceans!

A man dives of the deck of Michael Lucas's home on Fire Island Pines and into the Great South Bay (c) David Shankbone

To celebrate the launch of the brand new Naked Oceans podcast, we venture beneath the waves to investigate the impacts of oil spills on the marine environment.  We hunt down the hidden world of microbes in the Louisiana wetlands, trace the fingerprint of oil in the open oceans, and discuss the likely fallout from the Deepwater Horizon oil spill in the Gulf of Mexico.  We'll also be exploring the effects of a changing climate on marine habitats, finding out what warmer water means for life at the poles and meeting some of Antarctica's unique marine wildlife.  Plus, Carl Safina, President of Blue Ocean Institute explains why he would like to be a Bluefin Tuna!

  • 01:46 - Whales have to shout in noisy seas

    Acoustic tags attached to North Atlantic right whales in Canada's Bay of Fundy show that when the seas are noisier, the whales call louder - presumably to make themselves heard over the din.

  • 04:15 - More fish lurk in the deep than we thought

    There may be more fish living at extreme depths of the ocean than previously thought. And snailfish are caught on camera over 7km beneath the waves.

  • 05:57 - Cleaner water means healthier reefs

    Keeping local waters free from land-based pollutants can help coral reefs cope with problems like climate change offering - a perfect case of thinking globally and acting locally.

  • 07:27 - Census of Marine Life inventory

    This month an initial ‘roll call’ of what species are present in the 25 marine areas of the Census of Marine Life has been published in the journal PLoS One.

  • 09:27 - Gulf of Mexico spill and the Louisiana wetlands

    The Deepwater Horizon oil spill added to the long list of problems that already threaten the Louisiana wetlands. Robinson Fulweiler from Boston University tells us about the importance of these ecosystems including the vital, hidden world of wetland microbes.

  • 18:49 - Catching up with the Sea Empress Oil spill

    In 1996 the Sea Empress tanker ran aground spilling oil onto 120 miles of Welsh coastline. Helen visits West Angle Bay - one of the worst hit beaches - to meet Robin Crump and find out how the spill affected the rocky shores. And we meet a rare starfish that was almost wiped out...

  • 26:20 - Tracing the effects of oil in the open ocean

    Oil spills not only cause problems for the shores they wash up on but also impact open ocean ecosystems. Amy Hirons invites us into the planktonic world and tells us about her studies tracing the fingerprint of oil throughout the marine food web.

  • 34:34 - Climate change rundown

    Climate change poses many, varied threats to the oceans. John Bruno gives us a rundown of findings from his recent review of the topic in the journal Science.

  • 40:42 - Climate change in Antarctica

    David Barnes from the British Antarctic Survey tells about changes taking place in the Southern Ocean and introduces us to some amazing critters that have come a long way from home.

  • 49:11 - Life in Arctic Sea Ice

    As well as big animals like polar bears that hunt on top of Arctic sea ice, there is an extraordinary world of life living in the ice itself. David Thomas introduces these vanishing ecosystems and the challenges of studying them before they are gone.

  • 56:20 - Critter of the Week

    Blue Ocean Institute president, Carl Safina, chooses our first critter of the month.
