Have you heard of coral bleaching? That is what happens when corals lose their green or brown colored algae living inside of them due to environmental stress such as warmer temperatures. If conditions return to normal fairly quickly, the algae will come back; but if conditions change for too long then the coral will be permanently bleached and won’t be able to survive.
In the ocean, as on land, elements are constantly being cycled through different animals. An important player in this cycling process is bacteria. Bacteria can take organic matter, such as a fish carcass, and break it down to some of the essential compounds required for life. Bacteria sometimes get a dirty reputation, but they’re actually nature’s recyclers!
Hawaiʻian fishponds or loko iʻa, are a sophisticated method for raising a steady source of food that is accessible during storms and high surf when fishing can be dangerous. Perpetuating traditional fishpond practices is important to create more sustainable food resources in Hawaiʻi and ensure that such advanced cultural knowledge is not lost
SONAR, which stands for Sound Navigation and Ranging, is used on boats for navigation and to map out underwater landscapes. The world’s oceans are so vast, it would take 125 ships a full year to map the entire ocean floor with SONAR.
If you could take all of the bigger organisms of the ocean (whales, sharks, fish, squid) and add up their total weight, and then took all of the microscopic organisms (like plankton) in the ocean and added up their total weight, which one would weigh more? You might be surprised to hear that the microscopic organisms weigh over 40 times more than all other organisms in the ocean combined!
Photo: Oregon State University Salmon are an important member of the ecosystem, economy, and culture in the Pacific Northwest region of the United States. However, over the past several decades, wild populations of salmon in the region have decreased significantly, with many stocks listed as threatened or endangered under the US Endangered Species Act. In the 19th century, hatcheries for salmon were developed and now serve a role in providing salmon and steelhead stock for fisheries and contributing to conservation efforts. Although hatcheries show the potential to have a positive impact,... (more)
