Where the bottom is rocky and affords places for it to anchor, giant kelp forms extensive kelp beds with large "floating canopies". [8] When present in large numbers, giant kelp forms kelp forests that are home to many marine species that depend upon the kelp directly for food and shelter, or indirectly as a hunting ground for prey. Both the ...
Kelp forests are underwater areas with a high density of kelp, which covers a large part of the world's coastlines. Smaller areas of anchored kelp are called kelp beds . They are recognized as one of the most productive and dynamic ecosystems on Earth.
Giant kelp, Macrocystis pyrifera, the largest seaweed. Found in the Pacific coast of North America and South America. Kombu, Saccharina japonica (formerly Laminaria japonica) and others, several edible species of kelp found in Japan. Species of Laminaria in the British Isles; Laminaria digitata (Hudson) J.V. Lamouroux (Oarweed; Tangle)
Giant kelp marine forests are diverse, complex and highly productive components and foundation species of cold-water rocky marine coastlines around the world. Giant kelp marine forests in Australia are typically found in temperate south eastern waters on rocky reefs where conditions are cool and reasonably nutrient rich. [4]
Kelp forests are also some of the world's largest carbon sinks, and the Great Southern Reef therefore acts as a buffer against climate change. [7] Unfortunately, an estimated 95% of the giant kelp forests off the coast of Tasmania have died off over the past few decades due higher water temperatures and the long-spined sea urchin. [6] [8]
A welding hammer strapped to her wrist, Joy Hollenback slipped on blue fins and swam into the churning, chilly Pacific surf one fall morning to do her part to save Northern California's vanishing ...
An alternative offset would be to cultivate kelp forests. Kelp can grow at 2 feet per day, 30 times faster than terrestrial plants. Planting kelp across 10% of the oceans (4.5 x the area of Australia) could provide the same offset. Additionally, the kelp would support a fish harvest of 2 megatons per year and reduce ocean acidification. Large ...
However, a large part of the dinosaur fossil collection in Munich, including those from Egypt, fell victim to bombing during the Second World War. The only remnants of this 10-metre giant were Dr ...
