Effects of climate on marine primary production?
Regarding my theory about the lack of nitrogen... ...even if those declines could be proven, they would not provide support for your hypothesis. To get that, you would need to show that nitrate levels in the photic zone of the world ocean have fallen, roughly at the rate that protein has been removed from the sea. You have not done ...

Goods and services People have relied for millennia on the useful goods produced by marine ecosystems. Food, fibre, shells, medicines, chemicals - and now genes - are extracted, used, bartered and sold ...

Photosynthesis can only occur if the light intensity reaching the autotrophic cell (phytoplankton) is adequate. This means that light is a limiting factor in primary production. We already know that phytoplankton can only survive in the photic zone, where light penetrates the sea, and as you go deeper and deeper the light intensity decreases, until no photosynthesis ...

seaweed
Around 600 species are found on UK shores. Like land plants, all seaweeds depend on light for growth, so they only occupy the intertidal area or relatively shallow photic (light penetrating) zone. Green seaweeds tend to be found towards the top of the shore, browns from the top to deeper waters, and, since they ...
