New fossils of kelp holdfasts from early Oligocene rocks in Washington State show that kelps were present in the northeastern Pacific Ocean by at least 32 million years ago. [6] The organisms require nutrient-rich water with temperatures between 6 and 14 °C (43 and 57 °F).
At the federal level, H.R. 4458, the Keeping Ecosystems Living and Productive (KELP) Act, introduced July 29, 2021, seeks to establish a new grant program within NOAA for kelp forest restoration. [109] Ocean Rainforest, a Faroe Islands-based company, secured $4.5 million in U.S. government funding to grow giant kelp on an 86-acre farm off the ...
The species Pelagophycus porra, also known as elk kelp, grows in temperatures of no higher than 60 °F (16 °C). It grows in subtidal forests in the coastal waters off southern California and northwestern Baja California Peninsula , in waters of 20 metres (66 ft) to 90 metres (300 ft) deep, anchored by a holdfast in sedimentary or loose ...
[23] [24]: 8 They can grow at a rate of 60 cm (2 ft) a day to reach over 45 m (150 ft) long in one growing season. [8] [25] [26] Juvenile giant kelp grow directly upon their parent female gametophyte. To establish itself, a young kelp produces one or two primary blades, and begins a rudimentary holdfast, which serves to anchor the plant to the ...
Pelagic zones. The ocean can be conceptualized as being divided into various zones, depending on depth, and presence or absence of sunlight.Nearly all life forms in the ocean depend on the photosynthetic activities of phytoplankton and other marine plants to convert carbon dioxide into organic carbon, which is the basic building block of organic matter.

Juveniles stay in the kelp forest to protect themselves from predators. As they mature, they venture father into the open ocean. [10] They grow an average of 0.59 millimeters per day for the first 90 days of their lives. [13] Most of the kelp bass's growth takes place during the first few years of life, but they have indeterminate growth. [10]
