Summary: During the Pacific marine heatwave of 2014-2016, key forage fish species in the Gulf of Alaska experienced reduced abundance and quality, leading to trophic instability within the system. Despite compensatory changes in age structure, size, growth or energy content of forage fish, none were able to fully mitigate the adverse impacts of the heatwave. Changes in zooplankton communities and the impact on the forage fish community led to disruptions in the normal pelagic food web, causing shifts in distribution, mass mortalities, and reproductive failures among seabirds, marine mammals, and groundfish.

Summary: Pelagic sediments enriched in rare earth elements and yttrium (REY) have attracted significant attention. However, the mechanism responsible for this enrichment remains unclear due to challenges in obtaining robust geochronology. In this study, we integrated multiple geochronologic approaches to determine a chronostratigraphic framework for a pelagic sediment core collected from the northwestern Pacific Ocean. Our results indicate that REY-rich sediments were deposited prior to -2.5 Ma, with a highly REY-rich sediment layer deposited at -11.5-9.5 Ma. We propose that a low sedimentation accumulation rate and the contribution from active bottom currents are key factors in the enrichment of REY in pelagic sediments.

Summary: The traditional view that the benthic compartment is simpler in structure compared to the pelagic compartment is challenged in this study, which illustrates the presence of a subweb in the benthic realm with similar complexity to the pelagic counterpart, including megafaunal-predatory sea stars equivalent to iconic polar bears.

Summary: This paper provides an overview of graph-theoretic methods for analyzing the resilience of distributed control systems. It surveys distributed algorithms, quantifies the impact of attacks, and reinterprets system-theoretic notions from a graph-theoretic standpoint. These methods are important for addressing network attacks and faults in increasingly complex systems.

Summary: This study investigated the microplastic contamination and impacts in commercially important dolphinfish from the Eastern Pacific Ocean. Microplastics were detected in all fish, with an average of 9.3 particles per individual. The main chemical compositions of the microplastics were polyester, polyethylene terephthalate, polypropylene, polystyrene, polyethylene-polypropylene copolymer, and polyethylene. The study also suggested a potential interaction between microplastics and the reproductive function of the fish.

Summary: Environmental DNA (eDNA) metabarcoding was used to monitor fish populations in the central Pacific Ocean, revealing high diversity and significant differences in dominant species distribution. The study highlights the validity of eDNA technology for assessing pelagic fish biodiversity and provides foundational data for fish resource surveys in other ocean regions.

Summary: The study conducted a stock assessment of chub mackerel, Pacific saury, and Pacific sardine in the Northwest Pacific Ocean (NPO) using the length-based Bayesian evaluation (LBB) method. The results showed that the three species are currently in a healthy state and have not been overfished. The study also highlighted the efficiency of the LBB model in evaluating fisheries resources in the NPO, especially when only length frequencies are available.

Summary: The stranding of millions of pelagic red crabs along California beaches is related to anomalously warm waters and northward advection associated with El Nino. Research suggests that the pelagic red crabs may remain residents of northern waters for several years, with a source water index potentially serving as an early indicator for anomalous events in the future.

Summary: Coastal waters are biogeochemical hotspots globally, and the Northeast Pacific Coastal Temperate Rainforest (NPCTR) region is no exception. This study investigates the relative contributions of different ecosystems to surface ocean organic matter pools in the NPCTR, using a four-year dataset. The results show that the contributions vary seasonally and spatially, highlighting the need to consider coastal waters as integrated land-ocean meta-ecosystems.

Summary: Understanding genetic connectivity is crucial for species conservation decisions and fisheries management. A study on four endemic Lates species in Lake Tanganyika revealed strong genetic differentiation among the species, particularly within L. mariae. Further research is needed to explore the origins of genetic differentiation for conservation and management purposes.

Summary: This study investigated the presence and characteristics of microplastics (MPs) in the stomach of Dosidicus gigas squids collected from the tropical and Southern temperate Pacific. The study found that 50.0% of the squid specimens were contaminated with MPs, with an average abundance of 0.88 +/- 1.12 items/individual and 0.24 +/- 0.36 items/ g stomach weight. The MPs were primarily composed of polyethylene terephthalate, in the form of fragments and fibers, and were predominantly blue in color.

Summary: This study compared organic matter quantity and quality in abyssal plain sediments in different trophic states, revealing significant differences in biomass and distributions among regions. Nutrient-rich areas showed higher organic carbon content, higher oxygen uptake rates, while the opposite was observed in nutrient-poor regions.

Summary: Plastic pollution is a global concern and its impact on marine top predators, particularly endangered species, is not well understood due to limited data. This study examined the stomach contents of a poorly known endangered shark species, the longfin mako shark, and found plastic fragments and granules in the digestive system of its prey, suggesting trophic transfer. These findings highlight the vulnerability of the longfin mako shark to plastic ingestion and provide evidence of microplastic trophic transfer in shark species. The study emphasizes the need to evaluate the ecotoxicological consequences of increasing plastic pollution on endangered marine top predators.

Summary: This study analyzed the catch rates of immature and mature cohorts of bigeye tuna in the western and central Pacific Ocean, revealing synchronous shifts in pelagic ecosystems and the influence of the Pacific Decadal Oscillation as a bottom-up control regulator. The results showed a 3-year lag in low recruitment into the mature cohort after a decrease in the immature cohort's food stocks, demonstrating the impact of climate change on predator fish distribution and abundance.

Summary: Through studying the mercury concentrations in three tropical tuna species in the southwestern Pacific Ocean, it was found that there were significant inter-annual variability in mercury concentrations in tuna, but no clear long-term trend was observed. The influence of amino acids and model-estimated phytoplankton δN-15 values on mercury concentrations in tuna was highlighted.
