It is these instabilities that generate stronger currents, according to the study. Submesoscale currents are important because they create a corridor between ocean layers, allowing the upper ocean to exchange heat and carbon with the deep ocean in return for nutrients.
Where we depend on rainclouds to water our crops, phytoplankton and other marine organisms depend on these currents for their daily dose of nutrients. However, just as some seasons on land experience more rain than others, in the ocean, the currents in some seasons provide more nutrients than in others.
This provides a fertile environment for plants, fish, birds, and sea mammals. You can see a lot more activity on the water.
Birds are breeding during this season. Pelicans are flying everywhere. Along with other mammals and marine life, you will see some blue whales and humpbacks. You see fewer birds during the oceanic season, which is already underway, but more whales, dolphins, and sharks swimming about in the quiet sea. Between these two seasons — the time I find to be the most interesting — schools of anchovies, sardines, and the Pacific hake abound.
There is a feeding frenzy. I recently found myself on a beach off the Californian hamlet of Bolinas in the middle of a seasonal transition. For a couple of hours, I watched multiple whales frolicking in the waters as they dove for food. I am not enough of a nature expert to say for certain if these where the blue whales that have been making appearances in Northern California.
I could see these with my naked eye. It was easy to find them, as well, because the ocean was relatively calm. A gigantic, ever-changing swarm of sea birds was also taking part in this alfresco dining. The sight in front of me was a reminder of the gentle rotation of the planet, which will keep going long after I am gone.
Similarly, these whales will migrate elsewhere. Some of the same factors that affect the weather in the marine biome are water depth, salinity, and proximity to a land mass. Atmospheric weather patterns are less relevant in the marine biome than on land-based biomes because the majority of organisms in the marine biome live underwater. Shallow coastal ecosystems may be affected by storms and other weather events more than deep ocean ecosystems.
For example, a large rain event would cause excess runoff of fresh water from rivers to rush into the ocean, changing the salinity of the ocean water in a coastal area. Many people rely on the world's oceans for their livelihood. While atmospheric factors can greatly affect the conditions within the marine biome, so too can human activity. About 80 percent of all marine pollution is source from land-based activities. There are several possible long-term solutions for protecting the world's oceans from destructive human activities.
In order to protect marine biodiversity, it is necessary to establish protected areas such as national parks and reserves. Reducing destructive fishing practices and accidental fish kills such as dolphin caught in tuna nets would also help protect marine biodiversity and replenish fishing grounds. Minimizing the use of military sonar technology would protect whales and other marine mammals as well.
Emily Neal is a freelance science writer and nature photographer. She has a B. Phytoplankton utilize CO 2 from the atmosphere to build organic matter, and thus contribute to the biological carbon pump which sequesters CO 2 in the deep ocean. If as predicted by researchers, phytoplankton production is modified over the next decades, the capacity of the ocean to biologically sequester CO 2 could decline.
