Brine rejection is a process that occurs when salty water freezes. The salts do not fit in the crystal structure of water ice, so the salt is expelled. Since the oceans are salty, this process is important in nature. Salt rejected by the forming sea ice drains into the surrounding seawater, creating saltier, denser brine.
Sardine and pilchard are common names for various species of small, oily forage fish in the herring suborder Clupeoidei.

[19] The Peruvian anchoveta fishery is now the biggest in the world (10.7 million tonnes in 2004), while the Alaskan pollock fishery in the Bering Sea is the largest single species fishery in the world (3 million ...

A new study in the journal Frontiers in Toxicology found that microplastics in the fish we consume are far more widespread than you may think.. In late December, researchers from Portland State ...
Seawater, or sea water, is water from a sea or ocean.On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na +
About 3.5% of the weight of seawater comes from dissolved salts. But just how did the salt get in there? Why is the ocean salty? Lets dive in.
