We found that bacteria closely related to Alcanivorax became a dominant bacterial population in petroleum-contaminated sea water when nitrogen and phosphorus nutrients were supplied in adequate quantity. The predominance of Alcanivorax bacteria was demonstrated under three experimental conditions: (i) in batch cultures of sea water containing heavy oil; (ii) in columns packed with oil-coated gravel undergoing a continuous sea water flow; and (iii) in a large-scale tidal flux reactor that mimics a beach undergoing tidal cycles with fresh sea water. These results suggest that bacteria related to Alcanivorax are major players in the bioremediation of oil-contaminated marine environments.

Development of a non-invasive heart rate measurement method for sea turtles with dense keratinous scutes through effective electrode placement.

Measuring the heart rate of sea turtles is important for understanding their physiological adaptations to the environment. Non-invasive methods to measure the electrocardiogram (ECG) of sea turtles have been developed by attaching electrodes to their carapace. However, this method has only been applicable to sea turtles with sparse keratin on their shell surfaces, such as loggerhead turtles, and it is difficult to detect heartbeats in sea turtles with dense keratinous scutes, including green sea turtles.

Airborne wind energy is an emerging technology that can harness stronger and more consistent winds in higher altitudes using less mechanical and civil infrastructures than conventional wind energy systems. This article outlines a techno-economic study on using this technology for reverse osmosis seawater desalination in which a semi-permeable membrane process is used to remove salts and contaminants from water. To understand the techno-economic feasibility of such a system, this research work studies a 2 MW airborne wind-driven reverse osmosis plant.

Oil reservoirs are society's primary source of hydrocarbons. While microbial communities in industrially exploited oil reservoirs have been investigated in the past, pristine microbial communities in untapped oil reservoirs are little explored, as are distribution patterns of respective genetic signatures. Here, we show that a pristine oil sample contains a complex community consisting of bacteria and fungi for the degradation of hydrocarbons.

Diadromous fishes exhibit latitudinal clines of ocean dependency at inter- and intra-species levels. A pattern of ocean dependence at high latitudes and river dependence at low latitudes is explained by relative aquatic productivity. Such latitudinal productivity clines may induce geographical variations in life-history diversity within migratory phenotypes.

Unlike traditional passive optical remote sensing methods, ICESat-2 offers detailed vertical structure mapping of oceanic optical properties. Despite the potential of ICESat-2 for observing the optical vertical structure, its application in the East China Sea with complex hydrological conditions and dynamic ecosystems remains limited.
