Summary: Through the analysis of onshore cores, we have gained a deeper understanding of the stratigraphic architecture and sedimentary response of late Quaternary paleovalley systems. These systems experienced erosion during the late Pleistocene, filling during the Holocene, and basinwide flooding. The sediment characteristics indicate a shift in sediment provenance from southern Apennine rocks to a mixed composition from northern sources, due to the influence of the Southeast-directed Western Adriatic Current.

Summary: In recent decades, understanding of temperate carbonate systems has improved, but research on their development over glacial-interglacial timescales lags behind tropical systems. Analysis of sediment cores from Integrated Ocean Drilling Program Site U1460 off the Southwest Shelf of Australia reveals a record of sea-level controlled sedimentary cycles. The composition and texture of sediments deposited during interglacial highstands and glacial lowstands show distinct differences, suggesting regional variations in response to sea-level change.

Summary: By jointly inverting seismic wave data, this study constructed a 3-D Vs model of the upper crust beneath southeastern Australia, identifying sedimentary basins and low-velocity zones associated with different geological features. The findings suggest that sedimentary layers in the Murray Basin are less consolidated than those in the Sydney-Gunnedah-Bowen Basin, making the former more vulnerable to seismic hazards.

Summary: This study examines the breakup unconformities and rock record in the offshore NW Australia, finding that these unconformities are related to magma intrusion and continental crust breakup. The study supports the idea that the 'breakup unconformity' is not always a single stratigraphic surface marking the onset of seafloor spreading.

Summary: This research presents geomorphological and sedimentary data on the Salado-Juramento fluvial megafan in Northeast Argentina. It is the second largest megafan on the Chaco aggradational plain and one of the largest in the world. The study used a combination of methods including remote sensing analysis, field data collection, and historical document analysis to understand the morpho-sedimentary processes and Late Quaternary evolution of the region. The findings suggest that the megafan was formed by short-term sedimentation, channel avulsions, and interactions with the main river, controlled by tectonic and climatic factors. The data presented in this research is essential for making informed decisions regarding aquifer exploitation, land use, and infrastructure planning.

Summary: The study reveals that Lake Ebinur in central Asia experienced multiple hydroclimate changes during the late Quaternary, ranging from warm and humid conditions to cold and dry periods. Comparing the records with other regions in the Northern Hemisphere, it is found that central Asia exhibited similar moisture variability trends to the east Asia monsoon region, possibly due to common driving forces such as boreal solar insolation and Northern Hemisphere ice-sheet volume.

Summary: The Gippsland Basin is home to Australia's oldest offshore oil and gas structures. These structures, located in the Bass Strait, may have spillover effects on local fisheries and serve as de facto marine protected areas. By analyzing industry-collected ROV imagery and comparing it with catch data from fishing vessels, researchers found diverse communities of fishes and invertebrates around the structures. However, there was little overlap between the species targeted by commercial fishers and those found around the structures. Fishery-independent data greatly enhances our understanding of deepwater marine communities and provides valuable insights for future decommissioning scenarios.

Summary: Surface sediments from the Amazon river delta to the open marine sites in the north Atlantic Ocean were studied to characterize spatial differences in deposited organic carbon. The study utilized various biomarkers and stable isotopes to estimate the contributions of marine and continental sources to sedimentary organic carbon, revealing varying proportions of continental and marine OC along the transect. The results suggest that the river plume plays a significant role in stimulating primary production and deposition of marine organic carbon in the continental shelf and offshore sediments.

Summary: Isoprenoidal glycerol dialkyl glycerol tetraether (isoGDGT) lipids are mainly derived from archaea in the water column of Lake Lugano, Switzerland. The concentration of isoGDGTs, particularly Crenarchaeol, is higher in deeper waters below the thermocline. The distribution of isoGDGTs in surface sediments indicates downward transport from the water between the thermocline and the anoxic hypolimnion. The composition of isoGDGTs in surface sediments of other (peri-)alpine lakes varies based on lake size.

Summary: During the Miocene period, a large wetland system existed in western Amazonia that had unique sedimentary features and biological communities. The study conducted in Los Chorros site in Colombia revealed a sequence of flood-fill packages with distinct lithological, palynological, malacological and geochemical characteristics that reflect the changing environmental conditions in the wetland. Analysis of sediment sources and biomes indicate the influence of dynamic topography, Andean uplift, eustasy, and orbital forcing on sediment deposition and wetland evolution during the Miocene.

Summary: In acid drainage environments, moderately acidophilic sulfate-reducing bacteria (SRB) play a crucial role in attenuating extreme conditions by precipitating metals as sulfides and neutralizing acidity. A new species of moderately acidophilic SRB, Acididesulfobacillus acetoxydans gen. nov. sp. nov. strain INE, is identified with the ability to grow at pH 3.8. Bioreactor studies reveal that strain INE alkalinizes its environment, especially at lower pH, and has the ability to completely oxidize organic acids to CO2. Comparative proteogenomic and membrane lipid analysis suggest that the presence of saturated ether-bound lipids in the membrane serves as a protection mechanism against acid stress.

Summary: Bacterial membranes are composed of fatty acids (FAs) ester-linked to glycerol-3-phosphate, while archaea have membranes made of isoprenoid chains ether-linked to glycerol-1-phosphate. Some bacteria can produce ether-bound membrane-spanning lipids (MSLs), which are likely precursors of relevant molecules in paleoclimatology. The enzymes responsible for their production have been discovered, and the building blocks of these lipids are branched fatty acids. Phylogenomic analyses reveal a wider diversity of potential MSL-producing bacteria than previously thought, which has important implications for the evolution of lipid membranes.

Summary: The deep-sea environment is characterized by extreme conditions, including high hydrostatic pressure and near-freezing temperature. Piezophiles, microorganisms adapted to high pressure, have developed specific membrane lipid strategies to withstand these conditions, such as increased abundance of lipids containing unsaturated and branched-chain fatty acids with increasing hydrostatic pressure. However, not all piezophiles employ this strategy, highlighting the need for further understanding of the effects of hydrostatic pressure on microbial lipid membranes.

Summary: Interpreting lipid biomarkers in sediment archives requires a good understanding of their application and limitations. It has been discovered that marine bacteria performing anaerobic ammonium oxidation (anammox) synthesize a stereoisomer of bacteriohopanetetrol (BHT-x), which can serve as a proxy for water column anoxia. In the water column of the Benguela upwelling system, high BHT-x abundances were found in the oxygen-deficient zone, along with high abundances of Ca. Scalindua genes and ladderane intact polar lipids (IPLs). However, BHT-x ratios were low in oxygenated offshore waters. The BHT-x ratio of >= 0.2 is a robust threshold for oxygen-depleted waters.
