It’a tough to tease out what you are looking for. Have you tried googling: “Observing oceans algal blooms”? There’s lot of information out there.
The question i kept asking climatologists is why is that biosphere is no longer capable of absorbing those increased amounts of CO2? CO2 in air, and also in water acts as a fertilizer to plants and algae.
Why would a climatologist have the answer to that. You be better off asking a biologists.
It’s incorrect to claim our biosphere is no longer capable of absorbing increasing CO2. Our biosphere is plenty capable of absorbing increasing CO2 - the scary part is that in absorbing all that extra CO2 our biosphere as we know it will be irretrievably damaged as the increasing CO2 circulating throughout the system, altering the chemical process, increasing temperature stress, energized global hydrological cycle, and of course the amount of heat being retained within our global heat and moisture distribution engine.
If both statements are true, the question which remains is why we do not observe or measure increased growth of green plants (in general)?
Microalgae in phytoplanktom are the most important indication in this puzzle, as those represent largest mass of all plants.

Study Finds Plant Growth Surges as CO2 Levels Rise
Randall Donohue of the Commonwealth Scientific and Industrial Organization in Canberra, Australia, and his colleagues developed a mathematical model to predict the extent of this carbon dioxide fertilization effect.
Between 1982 and 2010, carbon dioxide levels in the atmosphere increased by 14 percent. So, their model suggested, foliage worldwide should have increased by between 5 and 10 percent.

Climate myths: Higher CO2 levels will boost plant growth and food production
By David Chandler and Michael Le Page - New Scientist
According to some accounts, the rise in carbon dioxide will usher in a new golden age where food production will be higher than ever before and most plants and animals will thrive as never before. If it sounds too good to be true, that’s because it is.
CO2 is the source of the carbon that plants turn into organic compounds, and it is well established that higher CO2 levels can have a fertilising effect on many plants, boosting growth by as much as a third.
However, some plants already have mechanisms for concentrating CO2 in their tissues, known as C4 photosynthesis, so higher CO2 will not boost the growth of C4 plants.
Where water is a limiting factor, all plants could benefit. Plants lose water through the pores in leaves that let CO2 enter. Higher CO2 levels mean they do not need to open these pores as much, reducing water loss.
However, it is extremely difficult to generalise about the overall impact of the fertilisation effect on plant growth.
Plants cannot live on CO2 alone
