Underwater cacophony caused by commercial and military ships has become so intense that it is killing whales, scientists at the World Conservation Congress say.

Hydropolis – Underwater Hotel
Hydropolis
No I’m not talking about a boring trip to the Aquarium or an episode of the Sopranos. No what I am referring to … is literally “sleeping with the fishes”. When one thinks about the future of travel, one might conjure up gaining passage on a rocket ship into space, the final frontier. Or that the honeymoons of the 21st century might actually entail a trip to the moon! Yes, yes… in all due course… I am sure that eventuality will happen. But what about exhausting the many unique features of terra firma before we actually decide to leave the planet? What about exploring the deep blue seas?

Another All Time Low For Arctic Ice
Picture is comprised of Envisat ASAR mosaics of the Arctic Ocean and highlights the changes in sea ice between June and mid-August 2008. The dark grey color represents ice-free areas while blue represents areas covered with sea ice.
Following last summer’s record minimum ice cover in the Arctic, current observations from ESA’s Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year.

“Interested Inhuman life, Octopus scientist reaches land to take observations”
An octopus attached itself to the side of a tank researchers used to sample ocean water from the surface to as deep as 2,500 meters and around hydrothermal vents. What the team discovered about the bacteria and viruses living around the vents surprised them ..

Robotic sea bream from the University of Kitakyushu
Engineers at the University of Kitakyushu have developed an underwater survey robot that looks good enough to eat. “Tai-robot-kun,” a 7-kilogram (15.4 lb) robotic sea bream (red snapper) with a silicone body covered in realistically hand-painted scales, features a unique propulsion system that allows it to move its tail and drift silently through the water like a real fish. Second video after the jump.

Sea Creatures In Antarctic Pounded By Icebergs
Large red sea spider walking over white hydroid at 25 m. Antarctic sea spiders can be up to 500mm across and have up to 12 legs.
Antarctic worms, sea spiders, urchins and other marine creatures living in near-shore shallow habitats are regularly pounded by icebergs. New data suggests this environment along the Antarctic Peninsula is going to get hit more frequently. This is due to an increase in the number of icebergs scouring the seabed as a result of shrinking winter sea ice. The results are published this week in the journal Science.

Self-Assembling City from the Sea – Autopia Ampere
German architect Wolf Hilbertz plans to use the process of electrodeposition to build a self-assembling city from the sea called Autopia Ampere.
Autopia Ampere will begin as a series of wire-mesh armatures anchored atop a sea mountain. Once in place, they will be connected to a supply of low-voltage direct current produced by solar panels. Over time, electrochemical reactions will draw minerals from the sea to the armatures, creating walls of calcium carbonate, which is what us landlubbers commonly call limestone.

Rubber Snake Generates Power From Waves
This new one is kind of a robot snake in reverse: it’s designed to float just beneath the surface of the sea and capture wave energy, which it then turns into electrical power.

World’s First Megawatt-Scale Tidal Turbine Installed
The power of the ocean without the smell of the sea
Marine Current Turbines Ltd, the global leader in tidal stream technology, has successfully completed the installation of its 1.2MW SeaGen tidal energy system in Strangford Narrows in Northern Ireland. There will now be a 12-week period of commissioning and testing before it starts regularly feeding power into the Northern Ireland grid.
