The Caitlin Seaview Survey plans on documenting the Great Barrier Reef and other world wide reef locations in great detail. It travels through the water at 4 kilometers per hour and takes a 360 panoramic image every four to six seconds, then geotaxis and puts the images together for better viewing on google earth and google maps. The launch of this Seaview starts in September 2012.
How do you think this will affect our knowledge of learning about the ocean?
How deep do you think this can go?
I am mostly interested in this article, describing what cuttlefish are. I find it very cool that the flamboyant cuttlefish can change colors, and how the lines move on the cuttlefish body. Most people say that they are the most advanced vertebrate found. Even though they are closely related to slugs, they have much better motor skills, sensory structures and highly developed heads.
Another example of their advanced body is their eyes. They are very similar to many other vertebrates which could help study eye evolution and functions. Cuttlefish have layers of color producing cells that work together to get different patterns. Which look awesome on flamboyant cuttlefish. The top three color pigments seen are black/brown, red/orange, and orange/yellow. I think that these fish should be protected because they are very cute and colorful. Do you think that the cuttlefish could be considered a violent endangered species?
I found this article on underwater ice tornadoes to be very interesting. Brinicles are supposedly columns of ice that are formed under calm ocean conditions, when there is a big difference between the water temp, which should be around -1.9C and the air temp which should be -20C. Which happens when the warmer water flows up to the air, freezing into new ice. According to the BBC, “the salt in this newly formed ice is concentrated and pushed into the brine channels. And because it is very cold and salty, it is denser than the water beneath.” Which creates brinicles. These tornadoes are found in both of the poles, and were filmed under the ice near Little Razorback Island near Antarctica.
Do you think this could cause a large decline in sea life near the poles?
Do you think these could grow into bigger tornadoes and effect more of the world?
So, I was reading this article about the rising sea level, and it says that the annual rate of sea level change is .13 in a year! Which would be 4-8 in every 20 years. Within the past century, burning of fossil fuels and other natural activities have released heat-trapping gases into the atmosphere. Which has caused the Earth’s surface temp to rise and oceans absorbing 80% of this additional heat.
These factors are causing the sea level to rise massively. Inland it can cause erosion, flooding of wetlands, contamination of aquifers & agricultural soils, loss of habitat for fish, birds, and plants. It can also cause larger storm systems to be more destructive. A recent study says that we can expect to see the ocean rise between 2.5ft and 6.5ft by 2100 ans will swamp most of the U.S. East Coast cities. And if there was a complete meltdown of the Greenland ice cap the sea level would rise to 23 feet. Which would be enough water to completely submerge London and Los Angeles.
*did you know there is enough water in the East Antarctic ice sheet to drastically change sea levels by 164 feet.
I think there is pretty much no way of stopping the sea level because of global warming, do you think we could take precautions and try to help slow the rising down?
What do you think would happen to all of the people living in the coastal areas of the world?
I read this article about a highly contagious marine influenza virus; Infectious Salmon Anemia. It has been reportedly found in the Pacific Ocean on British Columbia’s central coast. This virus was first found in Norway around 1984, also found in Eastern Canada in 1996, which has led to many of problems there. This virus was found in 2 of 48 sockeye smolts collected as a long term study on the plummet of river inlet sockeye populations. Another study found by the New York Times said that Chile has lost 2 billion because of the ISA, killing about 70% of their farmed salmon. Note; Chile does NOT have wild salmon! This virus does not affect humans!*
Do you think this virus could potentially hit our salmon fisheries soon?
Do you think ISA could spread throughout the entire ocean in the near future or in a while?
Scientists from the Monterey Bay Aquarium Research Institute in California have been studying Octopoteuthis deletion ( a species of squid ) in the murky depths of the eastern Pacific Ocean. They believe that it’s too murky to tell the difference between male and female for the squid. And the difference between them can only be determined by looking for a patch of wrinkled skin found on the females.
When the male finds a partner, he releases sperm packets to the other partner, which break into smaller sperm sacs that attach to the other squid’s mantle, fins, and arms. The scientists also found that after observing more than one hundred squid, that there were just as many male squid with sperm packets on them as females. And then the squid die shortly after mating..
Do you think that the species will become extinct fast if the male squid continue to mate with males and then die shortly after words?
Do you think this is a way of controlling their over populating species?
Scientists say that the March 11′ earthquake in Japan, literally moved the Japanese seafloor by 79feet, shaking it from east to west. The earthquake was the first time scientists have accurately measured such a outstanding movement of feet underwater. Scientists placed transponders on the seabed, using very careful sonar techniques to record the transponder’s locations, and also used research boats, whose locations were tracked by GPS satellites. A few weeks or so after the earthquake, the scientists returned to record the measurements.
“This is the first time a great subduction earthquake has been directly observed in the submarine part of the fault, which is where most of the action takes place,” noted Oregon State’s Goldfinger. “We normally have to infer slips from onshore GPS.” Goldfinger said.
Do you think this would change their local economy for fishing?
Do you think it would affect a large amount of sea life on their seafloor?
