Spatiotemporal concentration patterns for 19 parents and their alkyl homologues were measured in Pinctada radiata from 7 locations in the central Arabian Gulf around Qatar in the winter, spring and summer (2014-2015). The concentrations of PAHs ranged from 20 to 2240 (262 ± 38.0 ng·g dw) with the highest occurrence in the Doha harbor (738.

PAHs distribution was patchy with higher concentrations found inside semi-enclosed coastal areas like harbors and bays.

Concentrations of THg decreased in the order: liver˃muscle˃gonad. THg concentrations in fish tissue ranged from 0.

- A global database on seafloor biomass and abundance was created using data from 24 oceanographic institutions as part of the Census of Marine Life (CoML).
- A machine-learning algorithm called Random Forests was used to predict seafloor biomass based on factors like surface primary production and particulate organic matter, achieving 63% to 88% accuracy in explaining stock variance.
- The study found that biomass is highest near the poles and continental margins, while deeper areas like abyssal plains have lower values, with quality and quantity of food affecting species dominance and body size.
