An important consideration in our chapter was what topics we would cover and at what depth. B. Hollowed, A. C. Haynie, F. J. Mueter, and N. A. 17: Complex Systems, KM 1). Altieri, A. H., and K. B. Gedan, 2015: Climate change and dead zones. The goal when building the writing team for the Oceans and Marine Resources chapter was to assemble a group of scientists who have experience across the range of marine ecosystems (such as coral reefs and temperate fisheries) that are important to the United States and with expertise on the main drivers of ocean ecosystem change (temperature, deoxygenation, and acidification). In one experiment, scientists reduced the number of seaweed species. This is just one example of a food chain found in the marine ecosystem. Henson, S. A., C. Beaulieu, T. Ilyina, J. G. John, M. Long, R. Séférian, J. Tjiputra, and J. L. Sarmiento, 2017: Rapid emergence of climate change in environmental drivers of marine ecosystems. Most marine life inhabits this zone. Brown, W. Kiessling, P. J. Moore, J. M. Pandolfi, E. S. Poloczanska, A. J. Richardson, and M. T. Burrows, 2015: Climate velocity and the future global redistribution of marine biodiversity. At the surface of the ocean, the euphotic zone, the ecosystem receives plenty of light and oxygen, is fairly warm, and supports many photosynthetic organisms. Here, nutrients and salts from the ocean mix with those from the river in regions sheltered from extreme weather. The increase in intensity and occurrence of these toxic algal blooms has been linked to warm events in both the Atlantic and the Pacific.4,120,142 Abrupt warming was inferred to trigger the expansion of the North Pacific oxygen minimum zone through reduced oxygen solubility and increased marine productivity.225, Extreme events with corrosive (Ω < 1) and/or low oxygen conditions can occur when deep waters, which are generally corrosive and have low oxygen levels, are brought into the coastal area during upwelling. Burrows, M. T., D. S. Schoeman, A. J. Richardson, J. G. Molinos, A. Hoffmann, L. B. Buckley, P. J. Moore, C. J. The oceans play a pivotal role in the global climate system by absorbing and redistributing both heat and carbon dioxide.14,15 Since the Third National Climate Assessment (NCA3),16 understanding of the physical, chemical, and biological conditions in the oceans has increased, allowing for improved detection, attribution, and projection of the influence of human-caused carbon emissions on oceans and marine resources. These places are rich in nutrients from sediment brought in by the ocean. There has been progress in developing management strategies and technological improvements that can improve resilience in the face of long-term changes and abrupt events. Jewett, C.T. 16: International, KM 4).84, Changes in the timing of seasonal biological events can also impact the timing and location of fisheries activities. The top layer is called the euphotic zone, which receives lots of sunlight. 26: Alaska, Figure 26.4).50,51,52 Surface waters around Alaska have or will soon become permanently undersaturated with respect to calcium carbonate, further stressing these ecosystems (Ch. It is how animals, plants and the environment interact together and thrive. Experiments like this help us learn how reducing biodiversity can be extremely harmful to sensitive ecosystems. Coral reefs alone are home to over 25% of all marine life, despite occupying less than 1% of the ocean floor. A. Haley, P. Schrader, E. L. Brunner, M. W. Gray, C. A. Miller, and I. Gimenez, 2014: Saturation-state sensitivity of marine bivalve larvae to ocean acidification. A. A. Barth, C. A. Blanchette, R. H. Byrne, F. Chavez, O. Cheriton, R. A. Feely, G. Friederich, B. Gaylord, T. Gouhier, S. Hacker, T. Hill, G. Hofmann, M. A. McManus, B. As a result of that, the seagrass in those areas grew slower. Friedland, K. D., C. Stock, K. F. Drinkwater, J. S. Link, R. T. Leaf, B. V. Shank, J. M. Rose, C. H. Pilskaln, and M. J. Fogarty, 2012: Pathways between primary production and fisheries yields of large marine ecosystems. Phytoplankton is another important plant found in the ocean. tiny ocean animal, some of which secrete calcium carbonate to form reefs. van Hooidonk, R., J. Maynard, J. Tamelander, J. Gove, G. Ahmadia, L. Raymundo, G. Williams, S. F. Heron, and S. Planes, 2016: Local-scale projections of coral reef futures and implications of the Paris Agreement. Bell, R. J., J. A. Hare, and W. J. Overholtz, 2009: Changing spatial distribution of fish stocks in relation to climate and population size on the Northeast United States continental shelf. Broadly speaking, the marine ecosystem refers to the oceans and seas and other salt water environments as a whole; however, it can be divided into smaller, distinct ecosystems upon closer inspection. Brown, J. GarcÃa Molinos, B. S. Halpern, O. Hoegh-Guldberg, C. V. Kappel, P. J. Moore, A. J. Richardson, D. S. Schoeman, and W. J. Sydeman, 2016: Responses of marine organisms to climate change across oceans. Coral reefs are a diverse form of marine ecosystem, which in total may account for a quarter of all ocean species. In addition to warming, excess carbon dioxide (CO2) in the atmosphere has a direct and independent effect on the chemistry of the ocean.
