Summary: The oxygen content of the oceans has declined due to climate change, especially in oxygen-deficient zones. Climate warming simulations predict the expansion of these zones until at least 2100. The response of ocean oxygenation on longer timescales remains uncertain.

Summary: Research on loggerhead turtles in Mon Repos and Wreck Island revealed that scute uranium and blood molybdenum were significantly higher in Wreck Island turtles compared to Mon Repos turtles, while arsenic was higher in Wreck Island turtles foraging north and Mon Repos turtles foraging south. Additionally, significant correlations were found between certain trace elements and organic contaminants in eggs and blood.

Summary: Longline fishing vessels unintentionally catch endangered marine turtle species, such as green turtles, in the high seas. The stock composition of this bycatch is often complex and unknown, with individuals originating from different populations across the Pacific. To better understand the stock composition of green turtle bycatch, researchers collected 46 turtles caught by longline fishing vessels in the North- and South-central Pacific and used genetic analysis to determine their origins. The study found that turtle bycatch consisted of individuals from various breeding populations across the Pacific, suggesting overlapping geographic ranges during pelagic life stages.

Summary: This three-year study comprehensively characterized the concentrations of SF6 in the atmosphere and surface seawater, and found that polluted air masses from eastern Asian countries were the reason for the increase in SF6 concentrations in the study region. The ocean, as a significant sink of atmospheric SF6, has the potential to reduce its global abundance and environmental impacts.

Summary: Research conducted in the eastern North Pacific Ocean has revealed a correlation between high concentrations of floating plastic debris and certain neustonic species, suggesting potential plastic-associated fitness benefits. Higher plastic to organism ratios inside the North Pacific Garbage Patch indicate the negative impact of plastic pollution on the neuston.

Summary: This study estimated the distribution and abundance of loggerhead turtles in the Mediterranean Sea using aerial and shipboard line transect survey data. Two spatial density models were generated, providing valuable information for conservation planning and understanding basin-wide distribution and abundance patterns of this species.

Summary: The North Pacific Loggerhead sea turtle undergoes a significant migration from nesting grounds in Japan to foraging grounds in the eastern North Pacific, with a new hypothesis suggesting the existence of a thermal corridor connecting these habitats. By studying oceanography and tracking data, it was found that a small percentage of loggerhead turtles move eastward during anomalously warm ocean conditions, providing insights into recruitment pathways. The discovery of this potential thermal corridor offers the opportunity to explore the development of dynamic ocean pathways for this protected species, shedding light on a longstanding mystery in sea turtle ecology.

Summary: This case describes a juvenile Caretta caretta turtle with bilateral symblepharon, ankyloblepharon, and salt gland dysfunction. The turtle underwent surgical dissection of fibrous adhesions and removal of large dacryoliths, resulting in healing and restored vision in the affected eye. There were no recurrences after 12 months of follow-up, and the turtle was successfully released.

Summary: Long-term studies have shown that changes in seabird abundance and distribution are influenced by climate change and human activities. This study examined black-browed albatross and light-mantled sooty albatross observations over a 50-year period and found that climate indices, sea surface temperature, and sea surface height are the main drivers of their abundance and occurrence. The black-browed albatross showed a substantial decrease in abundance southeast of Australia, while no significant change was observed in the abundance of the light-mantled sooty albatross.

Summary: This study examines the impact of sea surface temperature on tuna catch in the Eastern Pacific Ocean countries, finding that catch increases with rising SST, with the highest catches in the eastern coastal borders. Mexico and Kiribati show significant differences in response to SST increase, while Kiribati and French Polynesia exhibit tuna catch revenue correlated with coastal population density.

Summary: In observations, it is clear that the boreal winter El Nino-Southern Oscillation (ENSO) phase-locking phenomenon occurs in the central-eastern Pacific. However, in the far eastern equatorial Pacific (FEP) and South American coastal regions, the peak of sea surface temperature anomalies (SSTA) tends to occur in the boreal summer rather than winter. This preference for summer peak is mainly contributed by the residual SSTA component, while the ENSO forcing has only a small probability of causing winter peak.

Summary: New data on the presence of trematode and nematode parasites in stranded loggerhead sea turtles in Sicily and the northwest Adriatic Sea were reported. The study showed a greater prevalence of digeneans, which can potentially cause severe damage to the turtles' internal organs. Analysis of variance highlighted significant differences in parasite prevalence among recovery sites.
