"Kelp forests are so sensitive," said Halpern. Giant kelp is harvested from kelp forests and used as a binding agent in products like ice cream, cereal, ranch dressing, yogurt, toothpaste, lotion and more.3 4. These additional areas also becoming marine parks. Overall, the global extent of kelp forests is on a downward trend because of ocean heatwaves, pollution, warming temperatures, and outbreaks of grazers like sea urchins. Hello Mike, It seems licensing is a serious issue regarding this particular topic.

The thing is, we have to slow down our polluting actives from CO2 to plastics. I have a proposal for removing gigatonnes of CO2 from the South Pacific Ocean and in doing so, reducing not only the acidity of the ocean but also reducing atmospheric CO2. Researchers are concerned that large-scale harvesting of kelp forests could have significant impacts, as they are an essential part of marine biodiversity. Some species aggregate and spawn in kelp forests or utilize these areas as juvenile nursery habitat. Sea urchins can destroy entire kelp forests at a rate of 30 feet (9 m) per month by moving in herds. A growing seaweed industry which produces a thickener used in food, textiles and pharmaceuticals has increased harvesting of kelp. By absorbing CO2 in the surrounding water, seaweed decreases acidification that can kill marine life. University of Adelaide. High energy storms or swells can uproot entire plants and break away fronds. Kelp monitoring projects actively continue in the four sanctuaries. The major kinds of pollution, usually classified by . This is the first study to put both variables together to see which is more important. Pollution, also called environmental pollution, the addition of any substance ( solid, liquid, or gas) or any form of energy (such as heat, sound, or radioactivity) to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. Theres only so much our planet can take before it reboots itself. At the. The Natural Gardener Inc. Research from 2016 suggests that the world's kelp forests sequester as much as 200 . See https://www.marinebiomass.com/ Im not sure the status of the work or the cost. by Sylvia Hurlimann There are about 30 different species of kelp worldwide. Switching people from meat to kelp or plant based would help our planet. The original paper reports tons of carbon, which is equivalent to about 600 tons of carbon dioxide. Kelp thrives in cold, nutrient-rich waters. This problem largely rests with us (human beings) in our pursuit to create useful products and different ways to power our machines. This is in part due to ocean warming, pollution, overgrazing, and coastal development. ShopPress Center Employment OpportunitiesContactFinancialsPrivacy PolicyTerms of Use, United StatesEuropeChileCanadaBelizePhilippinesBrazilPeruMexico, A great way to get involved in protecting #oceans: Join Oceana as a Wavemaker & sound off on important issues! Southpacificmarinepark.com covers this in the proposal. Warmer than normal summers and seasonal changes to currents that bring fewer nutrients to kelp forests (both sometimes occurring naturally) combine to weaken kelps and threaten their survival in some years. Kelp forests orchestrated by sea otters can increase commercial fishery harvests by up to six times. Blistering, bleaching and eventually degradation of the kelp's surface is impacting the species' ability to photosynthesise and potentially survive. In order to post comments, please make sure JavaScript and Cookies are enabled, and reload the page. Instead, bits of macroalgae get exported to the deep sea, where the carbon can be sequestered. "This work has shown that by reducing the nutrients we should be able to substantially reduce the impact of rising CO2. Many fish species use kelp forests as nurseries for their young, while seabirds and marine mammals like sea lions, sea otters and even gray whales use them as shelter from predators and storms.1, 4. The cycle between these so called urchin barrens and well-developed kelp forests is a well-studied phenomenon in regions that are favorable for forest formation. It has a similar structure to a plant, with a branching holdfast that roots it to the seabed, a thin hard stalk (called a stipe) and fronds that spread out like leaves. Is it possible to dry kelp without releasing CO2? Unless otherwise indicated, attribute to the author or graphics designer and SITNBoston, linking back to this page if possible. Unfortunately, because the carbon is stored close to the shore, it can be easily disturbed by runoff, human activity, or storms and released back into the atmosphere sooner than it otherwise might have. Kelp has an incredibly fast growth rate (up to two feet per day) and exports a large portion of its biomass out into the deep sea, allowing kelp to permanently remove carbon dioxide from the atmosphere. Though they look very much like plants, kelps are actually extremely large brown algae. Kelp looks like a tree, but it is a large brown algae. Some kelp species can measure up to 150 feet (45 m) long. The damage can sever kelp from its roots and cut the kelp off from ocean sediment nutrients. What if the kelp is grown for food? Kelp harvesting during World War I peaked in 1919 when 400,000 wet tons were used to make potash for gunpowder and fertilizer. Removing carbon dioxide from the atmosphere will play a necessary role in preventing rising temperatures and future climate catastrophe. Sign up today to get weekly updates and action alerts from Oceana. Where conditions are right, kelp can form dense underwater forests, which are among the most productive and . The team's findings, published on Oct. 22 in the journal JGR Oceans, show that near the ocean's surface, the water's pH was slightly higher, or less acidic, suggesting the kelp canopy does reduce acidity. They grow in dense groupings much like a forest on land, and are found predominantly along the Pacific coast from Alaska to parts of Baja California. Views expressed here do not necessarily reflect those of ScienceDaily, its staff, its contributors, or its partners. Kelp forests are found off coastal shores, which leaves them vulnerable to pollution from land. Fun Facts About Kelp Forests. Kelp is known for its size, it can grow up from the ocean floor and reach about 262 feet in length and grow as fast as 1.5 feet a day. During photosynthesis, kelps take carbon dioxide out of seawater which drives pH up in the local environment. Their rough estimate suggests that around 200 million tons of carbon dioxide are being sequestered by macroalgae every year about as much as the annual emissions of the state of New York. Self-confidence and very concern about the environment, I would like to work for a company which cares about nature and global warming challenge. Your email address will not be published. You can see kelp forests in many of . Runoff from agriculture, storm drains and urban wastewater carry contaminants that damage kelp populations and encourage the growth of invasive algae that . Https/Southpacificmarinepark.com "It's . The 2016 paper, coauthored by 37 scientists, concluded that "kelp forests are increasingly threatened by a variety of human impacts, including climate change, overfishing, and direct harvest." ALSO ON YALE E360 Feeling the Heat: How fish are migrating from warmer waters. "When we removed the nutrients but kept the CO2 high we found that after six months we'd reduced the turf algae by 75% -- we'd removed that synergistic effect," says Dr Russell. www.sciencedaily.com/releases/2013/07/130717095215.htm (accessed April 18, 2023). Im not a scientist but have been pondering for a while whether kelp could be grown at scale in the open ocean and then deliberately sunk as a method of carbon capture. I live on the South Coast of England ,up until the 60s our town had a large glass house horticultural Industry ,loose seaweed used to be collected from the beach and placed in jute sacks which was then immersed in large vats of water ,the water eventually turned into dark liqueur which was then poured on the crops. As in all ecosystems, a balance exists in this complex environment, and the predators such as sea otters generally contain sea urchins or grazing fishes enough to limit the damage by grazing. Kelp is the name given to several species of large brown seaweed. Oceana joined forces with Sailors for the Sea, an ocean conservation organization dedicated to educating and engaging the worlds boating community. 3 University of California, Santa Barbara. Im currently trying to look into whether large regional kelp farms set up as aquaculture facilities would sequester carbon or whether they need the full ocean environment to do so. Hi, It has supported a multitude of industries over the past century. Population sizes of many of these species (including some that are commercially important food species) depend on the success of kelp growth each year. Instead it secured by holdfasts to a rocky seafloor. Each of these natural alterations to kelp forest density or total area affects the community of invertebrates and fishes that live in this ecosystem. Because they contain unpalatable compounds, macroalgae remain mostly uneaten as they travels across the ocean. I have no substantial evidence as yet! Characterized by severe storms and warm water, El Nio Southern Oscillation Events, often devastate kelp forests. Sea urchins hide from otters in rock crevices. The planning link is broken could it be reposted? Kelp forests grow predominantly along the Eastern Pacific Coast, from Alaska and Canada to the waters of Baja, . 6. To achieve this will require the South Pacific Ocean becoming a marine park. Methane is a highly potent greenhouse gas which, although shorter-lived in the atmosphere, has a global warming impact 84 times higher than CO2 over a 20-year period. By most accounts, because of its spectacular growth rates, kelp recovers quickly from physical disturbances such as storms that might uproot the fragile plants. As macroalgae slowly degrade, they expel bits of DNA into the environment. Strong individual storms can wipe out large areas of kelp forest, by ripping the kelp plants from the seafloor. The method of removing the CO2 is a vast free-floating kelp forest ecosystem between New Zealand and South America and the key to growing this, is individual bamboo kelp buoys. Covers this in the proposal. Thanks, Did you ever get an answer to your questions about if can dry kelp without releasing Co2. Algin is an additive used in a wide variety of dairy products, frozen foods, cakes, puddings, salad dressings, shampoos, and toothpastes. But those actions can't cool warming oceans. "As we face a future of climate change and higher CO2 levels, there is considerable evidence that our marine ecosystems are going to be severely impacted. Materials provided by University of Adelaide. Sailors for the Sea developed the KELP (Kids Environmental Lesson Plans) program to create the next generation of ocean stewards. Genetic tools create new opportunities for decoding protein structures, The New Trojan Horse: Using tumor cells to kill tumors, According to the Intergovernmental Panel on Climate Change, https://myhomefarm.co.uk/state-shift-have-we-reached-the-tipping-point. For instance, high sedimentation from coastal run-off may bury new plant shoots. When otters are present, they control Sea urchin populations. Large gatherings of sea urchins (a primary herbivore in kelp forests) can prevent kelp plants from growing large enough to form forests. The effects of Climate Change are forcing farmers in Small Island Developing States (SIDS) to find novel methods to maintain crop productivity and sustainability. The kelp buoys carry the iron minerals required by the growing kelp plants and also assist the juvenile kelp plants to stay afloat. These estimations, however, rely on indirect calculations. Non-point and point source pollution including sewage, industrial disposal, and coastal runoff might contribute to kelp forest degradation. However, kelp harvest reached a high level during World War I, and currently does not appear to have major effects on ecosystem health. The proportion of kelp showing signs of bite marks increased from less than 10% in 2002 to more than 70% in 2008, before there was no kelp to measure. Additionally, some mariculture farms hand-harvest kelp to feed abalone. "People should have access to basic environmental resources that are important to them, and we need to know how these resources are changing and how those changes impact people . Through photosynthesis, kelp forests boost oxygen levels in the ocean while helping protect. Smith's team found that the otters were feeding on urchins in the remaining patches of kelp forest, but not in the urchin barrens. Losing our kelp forests would cause a ripple effect, impacting the many species that depend on them, says the organisation. https://www.greenwave.org/. Kelp forests comprise one the oceans most diverse ecosystems. (2013, July 17). Because kelp attaches to the seafloor and eventually grows to the waters surface and relies on sunlight to generate food and energy, kelp forests are always coastal and require shallow, relatively clear water. A new study evaluates their potential to ameliorate ocean acidification in sensitive coastal ecosystems. We have already protected nearly 4 million square miles of ocean and innumerable sea life -but there is still more to be done. We are restoring the worlds wild fish populations to serve as a sustainable source of protein for people. The impacts of predator loss and climate change are combining to devastate living reefs that have defined Alaskan kelp forests for centuries, according to new research published in Science . More studies are needed into the impact of kelp farming and . When the Endangered Species Act was passed 50 years ago, in 1973, some of North America's most iconic animals were on the brink of extinction. Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License, To read about carbon sequestration, check out, To learn more about the role of other marine ecosystems in sequestering carbon, read. Have you come across any other discussion of ideas of large scale kelp farming, expressly to capture and bury carbon? The combined warm water temperature and strong wave energy caused high mortality in the south. Area based management (e.g., designation of marine protected areas) is known to be an effective way to protect kelp forests from excessive use or harm by people. The major kinds of pollution, usually classified by environment, are air pollution, water pollution, and . Climate change increases harmful algal blooms Sugar kelp, the most commonly cultivated seaweed in the U.S., is grown mainly on longlines, or horizontal ropes, studded with spores that are submerged several feet below the water's surface. Kelp forests are underwater ecosystems formed in shallow water by the dense growth of several different species known as kelp. While the most effective way of doing this is by reducing carbon emissions, experts increasingly think that this will not be enough. These gas-filled bladders allow bits of macroalgae to float for long distances and be carried far away from where the macroalgae is grown. They even slow global warming.
