Pressing and drying seaweed To dry seaweed, simply arrange it on anything from trays to cookie sheets to screens. You can also dry large kelp by hanging them over railings or on laundry lines. Place them in a warm room, in the sun, or in a warm oven. These dried seaweeds can later be re-submersed in salt water to be studied.

Sep 8, 2023 · What is seaweed? Seaweed, or marine macrolagae, includes many different kinds of photosynthetic organisms. Some, like kelp and sea lettuce, are found in coastal areas where they cling to the ocean floor in areas shallow enough to receive sufficient light for photosynthesis. Others, like sargassum, float freely in the open ocean.

Selective breeding seaweed Using a mix of rulers, calipers, and measuring tapes, a dozen scientists—an aquaculture geek squad of sorts—are sizing up thousands of individual kelp blades recently harvested from offshore seaweed farms in New England in order to find the best specimens for selective breeding.

Ocean Encounters: Seaweed Solutions How scientists, ocean farmers, and policymakers are looking to kelp as a sustainable solution to some of the toughest issues facing our world today. As our climate continues to change and food insecurity grows worldwide, scientists and others are looking to solve these problems without harming marine ecosystems.

Jun 25, 2020 · Shellfish and seaweed aquaculture also provide valuable services to marine ecosystems and the planet. Shellfish and seaweeds absorb carbon dioxide rather than producing it like land-based livestock. In fact, dense seaweed farms can create a “halo-effect” around them that could help mitigate local ocean acidification.

Aug 20, 2020 · Phytoplankton are primary producers of the ocean—the organisms that form the base of the food chain. WHOI explores the microscopic, single-celled organisms.

Now more than ever, seaweed farming is being viewed as a sustainable and efficient way to boost economies, provide nutritious food, and diversify ocean life. Take a look at the work of WHOI’s Scott Lindell, a research specialist in aquaculture technology, leading a research project to develop seaweed strains for commercial uses.

Jun 10, 2024 · What are Currents, Gyres, and Eddies? Even on the calmest days, Earth's oceans are constantly on the move. At the surface and beneath, currents, gyres and eddies play a crucial role in physically shaping the coasts and ocean bottom; in transporting and mixing energy, chemicals and other materials within and among ocean basins; and in sustaining countless …

Jul 29, 2000 · Seaweed from one site contained nitrogen levels that matched those in sewage, and in peat removed through land clearing. Lapointe believes this shows that pollution from runoff and groundwater seepage has caused the growth of the seaweed.
