Resuspension of seafloor sediment by currents and wind. North Korea's known for its water-tight controls and relative isolation from the rest of the world. When sunlight penetrates the water, it encourages the growth of phytoplankton and algae. Whales are warm blooded marine mammals that can tolerate cold water temperatures. These measurements have shown changes in near-surface water clarity over decades. Feb 14, 2018. The good news is that there are things we can do to help improve water clarity and protect Orca populations. That would mean ocean dynamics in the area are different than we thought, said Rohan. Is Computer Peripheral Equipment a Good Career Path? This means that orcas may be more likely to hunt in areas with lower water clarity simply because there is a greater chance of finding their preferred type of prey. Alaska Fisheries Science Center Orcas, or killer whales, are toothed cetaceans that are the largest of the dolphin family. Some studies suggest that they do not rely on vision as heavily as other dolphins and whales, instead relying on echolocation (using sound waves to navigate and find prey).However, other studies have shown that orcas do use their eyesight to hunt for prey and avoid predators. Living in the sea poses a particular challenge to marine mammals, because water conducts heat about 25 times faster than same-temperature air. Clear Water Allows More Sunlight To Penetrate The Seabed, Providing Urchins With The Energy They Need To. The kelp can flourish, providing habitat for many ocean organisms. The Secchi disc is lowered into the water until it disappears, then pulled up until it can just barely be seen.
