Summary: Cold-water corals (CWCs) thrive in areas with complex and rough topography, but little is known about how basin-scale changes in the ocean climate affect their growth. In this study, high-resolution hydrodynamic models were used to investigate the impact of variations in basin-scale currents on local hydrodynamics and CWC communities. It was found that the variability of near-bottom currents and water mass properties at different AMOC states strongly influenced the CWC distribution. The kinetic energy dissipation rate was proposed as a mechanistic descriptor of CWC presence, providing insight into the hydrodynamics driving organic matter supply to these communities.

Summary: This study analyzed the composition and diversity of bacteria and archaea in deep-sea Fe-Mn crusts, nodules, and sediments from the Atlantic Ocean. The results showed that the microbiome of Fe-Mn deposits in the Atlantic seamounts had lower diversity and richness compared to the Pacific areas. Unique taxa and a higher abundance of potential metal-cycling bacteria were found in the crusts and nodules from Atlantic seamounts. The microbial beta-diversity was clearly grouped according to the microhabitats and geochemistry of the samples. These findings demonstrate the importance of microbial community analysis in environmental baseline studies for areas within the potential of deep-sea mining.

Summary: The study finds that sea surface temperature anomalies in both the tropical Atlantic and extratropical North Atlantic are related to the interannual variation of East Asian summer monsoon rainfall. These anomalies induce atmospheric teleconnections, leading to circulation anomalies over East Asia and subsequently modulating the monsoon rainfall. The results highlight the important role of Atlantic sea surface temperature anomalies in driving East Asian summer monsoon rainfall.

Summary: Natural pH values vary in coastal waters, and acidification trend is ongoing. This study found that pH does not affect the toxicity of organic contaminants to benthic organisms, but long-term exposure to low pH can impact estuarine nematode assemblages. This suggests that future coastal ocean acidification may push organisms closer to their tolerance limits.

Summary: This study analyzed the distribution and sources of isoprenoid glycerol dialkyl glycerol tetraethers (isoGDGTs) and branched glycerol dialkyl glycerol tetraethers (brGDGTs) in deep-sea sediments. The results revealed the contribution of benthic Thaumarchaeota to isoGDGTs in the seamount area and in-situ production of brGDGTs. The findings suggest the importance of considering both planktonic and benthic Thaumarchaeota in paleoceanographic reconstruction and highlight the discrepancy between sea surface temperature deduced by TEX86 and observed sea surface temperature.

Summary: Using data from an aquaculture monitoring program, this study investigates the presence of anti-sea lice drugs and their relationship with organic enrichment in sediment near salmon farms in Canada. The study finds that concentrations of the drugs are often below detection limits and lower compared to other countries. The highest concentrations are observed close to the cages, with lower concentrations detected up to 1.5 km away. Most samples contain multiple drugs, highlighting the potential for cumulative effects. The detection of drugs several years after treatment emphasizes the need for research on their overall persistence.

Summary: The study investigates the relationship between the Atlantic multidecadal variability (AMV) and atmospheric heat source over the Tibetan Plateau (TPHS), as well as their combined impact on the East Asian summer rainfall (EASR). Results show that the AMV has a remote effect on the EASR through an atmospheric teleconnection, and the TP plays a enhancing role in this effect. The TP amplifies the impact of the AMV on the EASR through the orographic effect and further strengthens the summer monsoon and the East Asian tripole rainfall pattern.

Summary: Improved representation of air-sea fluxes afforded by eddy-rich oceans in high-resolution coupled ocean-atmosphere models may modify the tracks and intensity of storms and their response to climate change. The increase in storminess associated with the eddy-rich model is six times greater than in the eddy-permitting model, with projections revealing greater warming in the western Atlantic.

Summary: Examining Fe speciation in marine sediments is essential for understanding Fe and carbon biogeochemical cycling in polar regions. This study investigated Fe speciation in sediments from Prydz Bay and the Southern Ocean and its relationship with TOC. The results show that Fe-U is the dominant pool of Fe-T, and Fe-HR/Fe-T ratios are low due to weak bedrock weathering and slow glacier melting. There are no significant correlations between TOC and Fe-HR, Fe-carb, Fe-ox1, or Fe-ox2 in the research region.

Summary: Mangroves, as one of the most productive ecosystems, are disappearing rapidly. Nematodes in mangrove sediments can serve as potential bioindicators, but due to the heterogeneity of mangroves, predicting their distribution and determining environmental drivers is challenging. The review examines the ecological mechanisms shaping nematode community at global, local, and micro scales, highlighting the positive influence of latitude on nematode genera richness and the role of mangrove trees in sediment chemistry variations. The use of functional traits remains inconsistent among studies, calling for further research on unexplored areas and microhabitats.

Summary: Antimicrobial peptides (AMPs), such as Alvinellacin (ALV), arenicin (ARE) and polaricin (POL), play a crucial role in the external immunity of animals and provide a model for studying the impact of the environment on the diversification and evolution of immune effectors. These AMPs possess a conserved BRICHOS domain in their precursor molecule, despite significant structural and amino acid diversification in the C-terminal portion. The study demonstrates that the bactericidal activity of these AMPs is optimal against bacteria found in their respective habitats, and the presence of disulfide bridges enhances their effectiveness in fluctuating environmental conditions.

Summary: The study investigated the Loricifera fauna along the Atacama Trench, and found four new species, two of Rugiloricus and two of Pliciloricus, on the continental slope and surrounding abyssal plains. Only one of the new species, Pliciloricus ukupachaensis sp. nov., could be formally described, and it showed close relation with Pliciloricus leocaudatus from the North Atlantic, but with different morphological traits. The new species has an enlarged anal field with conspicuous pentagonal and hexagonal fields, as well as reduced trichoscalid plates and no double trichoscalids. Comparison with unidentified specimens suggests a possible distribution range extending to Oregon off the US west coast.
