Microbiomes and biogeographic patterns. Links between microbiome and biogeography have been previously focused on several organisms, including marine sediment organisms46, humans47, pigs48, gastropods20, among others. The microbiome of marine species and marine sediments have revealed ...
In parts of the global ocean where the supply of Fe, either from the bottom (e.g., sediment and hydrothermalism) or the top (i.e., atmospheric deposition), is low, Fe becomes a micronutrient that limits the marine productivity. These oceans are often termed as the high-nutrient low-...
The Mariana Trench is the deepest place in the ocean and contains some fascinating animals. NOAA has made some exciting discoveries about life in the trench.
When classified by sediment lithology, predominantly siliceous sediments unsurprisingly have higher mean diffusive fluxes than predominantly calcareous or clay-rich sedi- ment. Combined with the areal extent of these lithologies, the `best-guess' global sedimentary bSi recycling flux is 69 9 1012 mol...
(e.g., sediment and hydrothermalism) or the top (i.e., atmospheric deposition), is low, Fe becomes a micronutrient that limits the marine productivity. These oceans are often termed as the high-nutrient low-chlorophyll (HNLC) regions such as the subarctic north Pacific, the east equatorial...

The Arctic Ocean (AO) is changing at an unprecedented rate, with ongoing sea ice loss, warming and freshening impacting the extent and duration of primary productivity over summer months. Surface microbial eukaryotes are vulnerable to such changes, but b
(Supplementary Data9). Thus, we used the XGBoost algorithm with the above combination of hyperparameters to construct the final classified model (accuracy = 99.09% on the training dataset and 98.31% on the test dataset). The high prediction accuracy of the machine learning models we ...
Why is freshwater biology important? How does weathering increase ocean salinity? How does sediment from rivers increase ocean salinity? Why is the marine biome important? How does salinity in estuaries promote biological productivity? Why are sea urchins important to coral reefs?
