DOI: 10.1016/j.jappgeo.2017.09.014
Abstract: Abstract There are many geological hazards in shallow formations associated with oil and gas exploration and development in deep-water settings. Abnormal pore pressure can lead to water flow and gas and gas hydrate accumulations, which… read more here.

DOI: 10.1073/pnas.2123544119
Abstract: Significance Most fish species live in shallow waters despite >90% of habitable ocean occurring in the deep sea. We show that present-day diversity patterns are the outcome of alternating phases over 200 million y that… read more here.

Diving Behavior and Fine-Scale Kinematics of Free-Ranging Risso's Dolphins Foraging in Shallow and Deep-Water Habitats
Sign Up to like & getrecommendations! Published in 2019 at "Frontiers in Ecology and Evolution"
DOI: 10.3389/fevo.2019.00053
Abstract: Air-breathing marine predators must balance the conflicting demands of oxygen conservation during breath-hold and the cost of diving and locomotion to capture prey. However, it remains poorly understood how predators modulate foraging performance when feeding… read more here.
