The deep-sea benthic fauna of Australia, especially asteroids found in depths greater than 1000 m, are poorly understood. Recent surveys have uncovered additional specimens that further illustrate the biodiversity of this largely understudied area. Two new genera and seven new species of Goniasteridae from deep-sea settings in Australian waters, including the South Pacific and Indian Ocean waters are described. A new genus, Alloceramaster was developed to accommodate not only the newly described species, but also other deep-sea species present in similar habitats from the Atlantic and the Pacific oceans. It addresses taxonomic shortcomings of Ceramaster, which has increasingly been used to accommodate other dissimilar species. Further occurrences of widespread deep-sea species, including Bathyceramaster teres, Litonotaster intermedius, Nymphaster moebi, and Sibogaster nieseni are also reported.

Sources, Pathways, and Drivers of Sub‐Antarctic Mode Water Formation

April 2025 · AGU Advances

Sub‐Antarctic Mode Waters (SAMWs) form to the north of the Antarctic Circumpolar Current in the Indo‐Pacific Ocean, whence they ventilate the ocean's lower pycnocline and play an important role in the climate system. With a backward Lagrangian particle‐tracking experiment in a data‐assimilative model of the Southern Ocean (B‐SOSE), we address the long‐standing question of the extent to which ... [Show full abstract] SAMWs originate from densification of southward‐flowing subtropical waters versus lightening of northward‐flowing Antarctic waters sourced by Circumpolar Deep Water (CDW) upwelling. Our analysis evidences the co‐occurrence of both sources in all SAMW formation areas, and strong inter‐basin contrasts in their relative contributions. Subtropical waters are the main precursor of Indian Ocean SAMWs (70%–75% of particles) but contribute a smaller amount (<

40% of particles) to Pacific SAMWs, which are mainly sourced from the upwelled CDW. By tracking property changes along particle trajectories, we show that SAMW formation from northern and southern sources involves contrasting drivers: subtropical source waters are cooled and densified by surface heat fluxes, and freshened by ocean mixing. Southern source waters are warmed and lightened by surface heat and freshwater fluxes, and they are made either saltier by mixing in the case of Indian SAMWs, or fresher by surface fluxes in the case of Pacific SAMWs. Our results underscore the distinct climatic impact of Indian and Pacific SAMWs formation, involving net release of atmospheric heat and uptake of atmospheric freshwater, respectively; a role that is conferred by the relative contributions of subtropical and Antarctic sources to their formation.

Genomes of Prochlorococcus, Synechococcus, bacteria, and viruses recovered from marine picocyanobact...

April 2025 · Scientific Data

Prochlorococcus and Synechococcus are key contributors to marine primary production and play essential roles in global biogeochemical cycles. Despite the ecological importance of these two picocyanobacterial genera, current genomic datasets still lack comprehensive representation of under-sampled ocean regions, associated bacteria and viruses. To address this gap, we used a combination of second- ... [Show full abstract] and third-generation sequencing technologies to assemble comprehensive genomic data from 105 Picocyanobacterial enrichment cultures isolated from the Indian Ocean, the South China Sea, and the western Pacific Ocean. This dataset includes 55 Prochlorococcus and 50 Synechococcus genomes with high completeness (>98%) and low contamination (<2%), along with 308 non-redundant associated bacterial genomes derived from 1,457 medium- and high-quality non-cyanobacteria metagenome-assembled genomes (MAGs, completeness ≥50% and contamination ≤10%). Additionally, 2,113 non-redundant viral operational taxonomic units (vOTUs) were derived from a total of 7632 qualified viral contigs. This dataset provides a valuable resource for improving our understanding of the complex interactions among Prochlorococcus, Synechococcus, and their associated bacteria and viruses in marine ecosystems, offering a foundation to study their ecological roles and evolutionary dynamics.

Establishment and Comparison of Two Types of Statistical Monthly Spatial Prediction Models for Wedde...

April 2025 · Journal of Climate

In recent years, the Weddell Sea ice loss accounted for nearly half of the Antarctic sea ice loss, whose prediction has attracted much attention. In this study, we developed two types of monthly spatial statistical prediction models for sea ice concentration (SIC) in the Weddell Sea, specifically the multiple linear regression (MLR) and multivariate empirical orthogonal function (MEOF) prediction ... [Show full abstract] models. Both prediction models shared a common set of advanced oceanic and atmospheric variables, including the Pacific decadal oscillation, eastern tropical Pacific Ocean sea surface temperatures (SSTs), western tropical Indian Ocean SST, southern tropical Atlantic Ocean SST, Antarctica sea level pressure, and Amundsen–Weddell dipole of surface air temperatures with the leading times of 1–57 month(s). The first-month Weddell SIC ahead of the predicting time was also individually incorporated or together with the 12th month advanced one as the predicting factors. Although the MEOF method is excellent at extracting the spatial mode of meteorological variables, it is unexpected that the MLR prediction model demonstrated enhanced performances. The median of the average anomaly correlation coefficient (ACC) of the MLR prediction model was up to 0.45 and that of the average RMSE was as low as 0.8, which was significantly better than those of 0.34 and 1.12 of the MEOF prediction model. This study highlights the advantages of the MLR prediction model and the importance of employing advanced sea ice to improve the spatial predictive performance of statistical models.

Characterising local climates and biologically-relevant climate changes on the Southern Ocean Island...

April 2025

The Southern Ocean climate has undergone significant changes over the last several decades, which has had consequences for conditions on the few small islands scattered across the region. Previous investigations of climate changes on the Southern Ocean Islands (SOIs) have examined single climate variables, such as temperature, and single islands or island groups. Furthermore, these studies have ... [Show full abstract] tended to focus on mean values without consideration of variability and extreme events. Consequently, we currently lack a comprehensive and up-to-date analysis of biologically-relevant climate changes that have occurred on these islands. Such insights are needed to determine the exposure of these unique and potentially fragile island ecosystems to climate change and the threats and challenges that their species will face. Here, we used weather station records to quantify the climate signature of SOIs and examine trends in a set of biologically-relevant climate parameters related to temperature, precipitation, and wind. We found that comprehensive warming has occurred across these islands but with important nuances, including differences in the rate of increase in minimum and maximum temperature contributing to an increase in diurnal temperature range. In contrast, precipitation changes have been highly localised, with severe drying on Marion and Crozet Islands in the Indian Ocean sector and wetting on Macquarie Island in the Pacific Ocean sector. Changes in wind speed have been idiosyncratic but have important consequences in combination with changes in other variables. Some of the implications of these changes for the SOIs are discussed.
