New studies show complex effects of carbon dioxide on fish population. Many studies have shown that larvae of various fish species can be negatively affected by ocean acidification. Acidification is caused by large amounts of carbon dioxide (CO2) entering the seawater from the atmosphere. But CO2 can also influence the food supply for the fish … more Obecnie poza Ziemią nie są znane żadne ciała niebieskie, na których potwierdzona byłaby obecność powierzchniowych zbiorników ciekłej wody. Prawdopodobnie przed 3-4 miliardami lat istniał ocean na Marsie, jednak utrata pola magnetycznego i rozrzedzenie atmosfery planety przyczyniły się do jego zaniknięcia. Plastic is everywhere – even the deepest parts of the ocean are now awash with it. The mesopelagic area of the ocean plays a crucial role in marine ecosystems, but it has remained largely untouched and unexplored But now some nations are eyeing the deep sea as potentially rich new fishing grounds.24 days ago Most studies looking at how corals will respond to future increases in ocean acidity are based on laboratory studies. This week in the journal Nature, researchers reported on a large-scale experiment to simulate these conditions in a natural coral ecosystem. Scientists have attributed an algal bloom that killed off $800 million worth of salmon in Chile to rising ocean temperatures, and they say other aquaculture operations around the world are at risk.about 1 month ago The ocean has a significant effect on the biosphere. Oceanic evaporation, as a phase of the water cycle, is the source of most rainfall, and ocean temperatures determine climate and wind patterns that affect life on land. Life within the ocean evolved 3 billion years prior to life on land. Both the depth and the distance from shore strongly influence the biodiversity of the plants and animals present in each region.[41] The amount of noise in the ocean has doubled each decade since the 1950s. A school of 6 cod fish swimming in an ocean. OceanSITES is a worldwide system of long-term, open-ocean reference stations measuring dozens of variables and monitoring the full depth of the ocean from air-sea interactions down to the seafloor. It is a network of stations or observatories measuring many aspects of the ocean’s surface and water column using, where possible, automated systems with advanced sensors and telecommunications systems, yielding high time resolution, often in real-time, while building a long record. Observations cover meteorology, physical oceanography, transport of water, biogeochemistry, and parameters relevant to the carbon cycle, ocean acidification, the ecosystem, and geophysics. Though generally described as several separate oceans, the global, interconnected body of salt water is sometimes referred to as the World Ocean or global ocean.[15][16] The concept of a continuous body of water with relatively free interchange among its parts is of fundamental importance to oceanography.[17] What is it like to stand on the ocean floor? What do you learn from a lifetime spent in the heart of the sea?  Fish are catchable when fishing using a fishing pole. They can be found in the ocean, lake or river, and some are unique to either day or night or only appear when it rains. Fish are used in cooking and the fishing community center bundles. The length of each fish type is recorded, and viewable on the collection screen. But today the ocean’s reserves are overdrawn, threatening countless communities around the world with climate, economic, and food insecurities. Unsustainable development, fueled by human population growth, has weakened ocean ecosystems. Modern technology is accelerating the rate of change. Earth may be the blue planet, but beneath the ocean waves lies a vast forest of green.  Lanternfish are one of many animals that light up the ocean with their glowing bodies. Pledge to work together to solve the world’s greatest environmental problems and protect our oceans. Istnienie oceanu na księżycu Saturna zwiększa szanse na znalezienie życia pozaziemskiego w naszym Układzie Słonecznym. Not enough is known of the larger trans-Neptunian objects to determine whether they are differentiated bodies capable of supporting oceans, although models of radioactive decay suggest that Pluto,[69] Eris, Sedna, and Orcus have oceans beneath solid icy crusts approximately 100 to 180 km thick.[66] Cod: Normal, cold, lukewarm oceans and deep variants Salmon: Normal, frozen rivers, cold, frozen oceans and deep variants Puffer Fish: Lukewarm, warm oceans and lukewarm deep oceans Tropical Fish: Lukewarm, warm oceans and lukewarm deep oceans Heirs to Our Oceans is a rising tide of young leaders around the globe who are taking the ocean crisis into their own hands, educating themselves and others, bringing hope and solutions to the surface, and creating waves of change that will ensure the health of our blue planet for their generation and for future generations. There’s an emerging scientific consensus that the tracts of ocean floor in line to be mined – whether hydrothermal vents or fields of nodules – are thriving habitats with intricate ecosystems. And they are still largely unknown. +44 (0)20 7292 6161 Terms & Conditions Wiatry wiejące nad rozległymi obszarami wodnymi powodują powstawanie na powierzchni oceanu fal. Katastrofalne zjawiska, takie jak podwodne trzęsienia ziemi, wybuchy wulkanów czy rozległe osuwiska wywołują niszczące fale tsunami. Znacznie rzadziej tsunami może powstać na skutek upadku planetoidy, która trafi w powierzchnię oceanu. The ocean is not only home to dolphins and jellyfish, whales, and sharks. It’s also a museum where stories about life on the sea, not recorded in the books, are discovered. Uncover the human stories behind shipwrecks, including some of the most famous ones, including the Titanic. Are you ready to go back in time? Tune in to Ocean Today’s latest “Full Moon” video collection! We understand that the oceans impact every aspect of our lives and we see the power in every moment to change the future of our planet. Through music, mobile gaming and digital platforms. We see a new way to educate. Earth may be the blue planet, but beneath the ocean waves lies a vast forest of green.  A zone of rapid salinity increase with depth is called a halocline. The temperature of maximum density of seawater decreases as its salt content increases. Freezing temperature of water decreases with salinity, and boiling temperature of water increases with salinity. Typical seawater freezes at around −1.9 °C at atmospheric pressure. If precipitation exceeds evaporation, as is the case in polar and temperate regions, salinity will be lower. If evaporation exceeds precipitation, as is the case in tropical regions, salinity will be higher. Thus, oceanic waters in polar regions have lower salinity content than oceanic waters in temperate and tropical regions.[55] Our living planet is only as healthy as its oceans. These vast bodies of water cover more than two-thirds of Earth’s surface and are home to some of our most spectacular and treasured life. Oceans regulate our climate, produce half the oxygen we breathe, fuel the water cycle that produces rain and freshwater, sustain the livelihoods of millions, and provide nourishment for nearly 3 billion people. But the Foresight Future of the Sea Report for the UK government said there are also opportunities to cash in on the “ocean economy”. The federal government and private sector’s co-investment in the Ocean Supercluster positions Canada to become a global leader in the knowledge-based ocean economy. Terrestrial planets will acquire water during their accretion, some of which will be buried in the magma ocean but most of it will go into a steam atmosphere, and when the atmosphere cools it will collapse on to the surface forming an ocean. There will also be outgassing of water from the mantle as the magma solidifies—this will happen even for planets with a low percentage of their mass composed of water, so “super-Earth exoplanets may be expected to commonly produce water oceans within tens to hundreds of millions of years of their last major accretionary impact.”[73] Agitated Ocean – ciemny turkus przytłumiony błękitem, z którym odkryjesz ocean możliwości.
