Summary: The Atlantic meridional overturning circulation (AMOC) plays a significant role in the global distribution of heat, dissolved oxygen, and carbon in the ocean. This study used microbial source indicators from the Cenozoic Northwest Atlantic Ocean to infer changes in AMOC-driven deep-ocean oxygenation. The findings suggest a close association between the inception of Antarctic glaciation and AMOC, highlighting the importance of vertical mixing and wind-driven upwelling in the Southern Ocean for establishing AMOC as a key agent of deep-ocean ventilation.

Summary: The TEX86 paleothermometer is widely used for reconstructing past sea water temperatures, but the specific export depths represented by this proxy are still unclear. Through studying paleotemperature proxies from two pairs of closely located cores from Chilean and Angola margins, this study provides new insights into constraining the depths recorded by the TEX86 proxy. The study shows that the TEX86 records were statistically indistinguishable between the core sites, indicating the usefulness of this approach for paleo-reconstructions.

Summary: This study investigates the climate change mechanisms and factors influencing the middle Eocene climatic optimum through the assessment of sedimentary and geochemical data in the northern Peri-Tethys region. The results suggest that the significant organic carbon burial in the Kuma Formation played a quantitative role in the termination of the middle Eocene climatic optimum. Furthermore, the study highlights the importance of the interplay between global climate and regional oceanic evolution.

Summary: This study examines the transport bias of lipid-biomarker-based SST proxies in the Mediterranean Sea and finds that lateral transport has a negligible impact on the uncertainties of the two commonly applied proxies.

Summary: The North Water Polynya (NOW) in Baffin Bay is a highly productive region and a crucial moisture source for local ice sheet sustenance. This study analyzed lipid biomarkers in modern surface sediment samples to better understand the functionality of paleoceanographic proxies. The results show strong correlations between highly branched isoprenoids and a higher concentration of sterols in the NOW, providing new insight into past development and downcore reconstructions.

Summary: The study presents a method to determine the hydrogen isotopic composition of lipids using high-temperature gas chromatography on a modified GC/P/IRMS system. The results show that the method is suitable for determining the δH-2 values of various high molecular weight compounds such as TGs and GDGTs, expanding the possibilities for biomarker and food stable isotope analyses. Initial measurements suggest that bacterial and archaeal GDGT δH-2 values may reflect environmental and ecological conditions.

Summary: Unusual H-Shaped branched and isoprenoidal glycerol monoalkyl glycerol tetraethers (GMGTs, or H-GDGTs) have been found in peat, lake, and ocean sediments. Relationship between the abundance of H-GDGTs relative to regular GDGTs and temperature, however, has not been widely explored. Results from peat cores in northeastern China show that high relative abundances of H-brGDGTs are associated with high temperatures, while high relative abundances of H-isoGDGTs are generally associated with low temperatures. These findings are partly inconsistent with observations from a modern global peat database.

Summary: This study presents a high-resolution carbonate C-isotope stratigraphy for the Aptian in the Cau core (Spain) and focuses on the early Aptian Oceanic Anoxic Event (OAE 1a). It reveals a record of pulses of volcanism and methane emissions through sharp delta C-13(carb) negative spikes. The C-isotope profile across OAE 1a perfectly records the defined segments worldwide and proposes the Cau core as a new reference section for the Aptian.

Summary: Oil refineries contribute up to 5% of global CO2 emissions, with a significant portion coming from the Fluid Catalytic Cracking (FCC) process. A study has investigated the combustion behavior of different types of cokes using oxygen carriers CuO, Co3O4, and Mn2O3. The results show that CuO is the most effective carrier at high temperatures and can achieve high combustion efficiency.
