We compare two marine sediment cores collected from contrasting locations in Kane Basin, northwest Greenland. The two sites differ in terms of sedimentation rates, primary production, and organic matter composition and source. Despite these spatial differences, both records reveal a similar long-term trend, a shift from cold, heavy sea ice influenced conditions between ca. 1750–1900 CE, towards more open, fresher, and biologically productive waters beginning around 1950 CE.

This article presents a non-destructive method for studying laminated sediments with X-ray micro-computed tomography (μCT). It aims to study the possibility of using μCT as an analytical tool to analyse varved sediments in the context of paleoclimatic studies. As a result, µCT offers the possibility of doing fast analysis and constitutes a powerful tool to improve the quality of results through the access of a 3D view, allowing for choosing the most representative part of a varved record.

A new 1500-year-long sediment record entirely made of annual laminations (varves) from a deep lake in Labrador was analyzed to perform a reconstruction of past hydroclimatic conditions. The varve thickness was linked to regional snow and rain precipitations. Our record indicates more precipitations during the 1050–1225 CE period, that is corresponding to the Medieval Climate Anomaly, whereas the 15th–19th centuries, related to the Little Ice Age, shows a drier climate.

We present an unprecedented record of Indian summer monsoon (ISM)-induced vegetation changes for MIS 11, a key interglacial. Site U1446 pollen data and models show that ISM-vegetation shifts stem from an interplay of dominant forcings based on boundary conditions. Insolation is the main driver during MIS 11c interglacial conditions, akin to future scenarios, while ice volume and CO₂ prevail in the glacial inception. Superimposed changes are marked by prominent forest contractions and expansions.

Along the French coast facing the Bay of Biscay, the large Gironde and Loire estuaries suffer from hypoxia. This prompted a study of the small Charente estuary located between them. This work reveals a minimum oxygen zone in the Charente estuary, which extends for about 25 km. Temperature is the main factor controlling the hypoxia. This calls for the monitoring of small turbid macrotidal estuaries that are vulnerable to hypoxia, a risk expected to increase with global warming.

This paper presents a dataset acquired during a research cruise held in Baffin Bay in 2016. We observed that the disappearance of sea ice in the Arctic Ocean increases both the length and spatial extent of the phytoplankton growth season. In the future, this will impact the food webs on which the local populations depend for their food supply and fisheries. This dataset will provide insight into quantifying these impacts and help the decision-making process for policymakers.

We explore the potential for the use of carbon isotopes of algal fatty acid as a new proxy for past primary productivity in Antarctic coastal zones. Coastal polynyas are hotspots of primary productivity and are known to draw down CO2 from the atmosphere. Reconstructions of past productivity changes could provide a baseline for the role of these areas as sinks for atmospheric CO2.

The MALINA oceanographic expedition was conducted in the Mackenzie River and the Beaufort Sea systems. The sampling was performed across seven shelf–basin transects to capture the meridional gradient between the estuary and the open ocean. The main goal of this research program was to better understand how processes such as primary production are influencing the fate of organic matter originating from the surrounding terrestrial landscape during its transition toward the Arctic Ocean.

A very high quality 160-year-long annually laminated (varved) sediment sequence of fluvial origin was recently discovered in an especially deep lake in Labrador. Each varve represents 1 hydrological year. A significant relation between varves' physical parameters (i.e., thickness and grain size extracted from each annual lamination) and river discharge instrumental observations provided the opportunity to develop regional discharge reconstructions beyond the instrumental period.

We present a multi-proxy record of Holocene glacial meltwater input, sediment transport, and sea-ice variability off East Antarctica. Our record shows that a rapid Antarctic sea-ice increase during the mid-Holocene (~ 4.5 ka) occurred against a backdrop of increasing glacial meltwater input and gradual climate warming. We suggest that mid-Holocene ice shelf cavity expansion led to cooling of surface waters and sea-ice growth, which slowed basal ice shelf melting.

In this study, we present RainNet, a deep convolutional neural network for radar-based precipitation nowcasting, which was trained to predict continuous precipitation intensities at a lead time of 5 min. RainNet significantly outperformed the benchmark models at all lead times up to 60 min. Yet an undesirable property of RainNet predictions is the level of spatial smoothing. Obviously, RainNet learned an optimal level of smoothing to produce a nowcast at 5 min lead time.

By studying microfossils from sediments in Upernavik Fjord we investigate the role of ocean warming on the retreat of Upernavik Isstrøm during the past ~90 years. The reconstruction of Atlantic-derived waters shows a pattern similar to that of the Atlantic Multidecadal Oscillation, corroborating previous studies. The response of Upernavik Isstrøm to ocean forcing has been variable in the past, but the current retreat may be temporarily tempered by cooling bottom waters in the coming decade.

A large quantity a continental material is transported to the oceans by the world rivers. Once in the ocean, these particles can be transported down the continental shelf thanks to underwater avalanches. The repetition of such massive events can form very important sedimentary deposits at the continent–ocean transition. Data obtained during an oceanic cruise in 2010 allowed us to study such a system located offshore of Gabon and to evaluate the importance sediment transport in this area.

Modifications in ice-stream networks have major impacts on ice sheet mass balance and global sea level. However, the mechanisms controlling ice-stream switching remain poorly understood. We report a flow switch in an ice-stream system that occurred on the Baffin Island shelf through the erosion of a marginal trough. Up-ice propagation of ice streams through marginal troughs can lead to the piracy of neighboring ice catchments, which induces an adjacent ice-stream switch and shutdown.

In oxygen minimum zone, the fate of the organic matter is a key question as the low oxygen condition would preserve the OM and thus enhance the biological carbon pump while the high microbial activity would foster the remineralisation and the greenhouse gases emission. To investigate this paradigm, sediment traps were deployed off Peru. We pointed out the influence of the oxygenation as well as the organic matter quantity and quality on the carbon transfer efficiency in the oxygen minimum zone.

Melt ponds (MP) forming over first year ice (FYI) represent a potential source of the climate-relevant gas dimethylsulfide (DMS) to the atmosphere. Nine MP were sampled in the Canadian Arctic Archipelago. DMS concentrations reaching up to 6 nmol L−1, twice the world's surface oceanic mean, were measured. Seawater intrusion appeared to seed MP with DMS-producing communities. DMS flux from Arctic MP is expected to increase in response to the expanding areal and temporal trends of MP on FYI.

The sources of aerosol particles and their growth to sizes large enough to act as cloud droplet seeds is of major importance to climate since clouds exert substantial control over the atmospheric energy balance. Using ship-board measurements from two summers in the Canadian Arctic, aerosol formation events were related to co-sampled atmospheric and oceanic parameters, providing insight into factors that drive particle formation and motivating further study of ocean–atmosphere interactions.

Diatoms and biomarkers have been recently used for palaeoclimate reconstructions in the Southern Ocean. Few sediment-based ecological studies have investigated their relationships with environmental conditions. Here, we compare high-resolution sedimentary records with meteorological data to study relationships between our proxies and recent atmospheric and sea surface changes. Our results indicate that coupled wind pattern and sea surface variability act as the proximal forcing at that scale.

Amongst the most devastating marine catastrophes that can occur in coastal areas are storms and tsunamis, which may seriously endanger human society. In a sediment core from the Mar Menor (SE Spain), we discovered eight coarse-grained layers which document marine incursions during periods of intense storm activity or tsunami events. These periods of surge events seem to coincide with the coldest periods in Europe during the late Holocene, suggesting a control by a climatic mechanism.

This study aims to analyse for the first time suspended sediment dynamics in the fluvial Gironde through a unique set of a 10-year continuous turbidity record. We demonstrate the following: the interest of turbidity-discharge hysteresis loops to evaluate the presence of sediment depositions; the relationships between features of the turbidity maximum zone (TMZ) and river flow; and the definition of hydrological indicators of the persistence and concentration of the TMZ.

Sea ice is important to stabilize the ice sheet in Antarctica. To understand how the global climate and sea ice were related in the past we looked at ancient molecules (IPSO25) from sea-ice algae and other species whose dead cells accumulated on the ocean floor over time. With chemical analyses we could reconstruct the history of sea ice and ocean temperatures of the past 14 000 years. We found out that sea ice became less as the ocean warmed, and more phytoplankton grew towards today's level.

Short summary
We present our results from a radiocarbon-dated core collected in central Nares Strait, NW Greenland. Sedimentological and geochemical data reveal that marine sedimentation began ca. 9.0 cal ka BP with the complete opening of the strait occurring at 8.3 cal ka BP. The collapse of the glacial buttress in central Nares Strait led to accelerated glacial fluxes of the bordering ice sheets between 8.3 and 7.5 cal ka BP, while the Humboldt Glacier retreated in eastern Kane Basin ca. 8.1 cal ka BP.
