Geologists can decipher the past climates and thus better understand how future climate change may affect the Earth's complex systems. In this paper, we report on a workshop held in Longyearbyen, Svalbard, to better understand how rocks in Svalbard (an Arctic archipelago) can be used to quantify major climatic shifts recorded in the past.

We provide a sea surface temperature record from the Labrador Sea (ODP Site 647) based on organic geochemical proxies across the late Eocene and early Oligocene. Our study reveals heterogenic cooling of the Atlantic. The cooling of the North Atlantic is difficult to reconcile with the active Atlantic Meridional Overturning Circulation (AMOC). We discuss possible explanations like uncertainty in the data, paleogeography and atmospheric CO2 boundary conditions, model weaknesses, and AMOC activity.

The Eocene–Oligocene transition was a major climate cooling event from a largely ice-free world to the first major glaciation of Antarctica, approximately 34 million years ago. This paper reviews observed changes in temperature, CO2 and ice sheets from marine and land-based records at this time. We present a new model–data comparison of this transition and find that CO2-forced cooling provides the best explanation of the observed global temperature changes.

This study provides an age model based on dinocysts for the early Oligocene succession from the North Sea. The changes in the dinocysts assemblage show that the succession was deposited in a proximal and dynamic environment. Furthermore, the results suggests that the early icehouse climate played an important role in the depositional development of the Oligocene succession in the North Sea basin.

We developed an online, open-access database for taxonomic descriptions, stratigraphic information and images of organic-walled dinoflagellate cyst species. With this new resource for applied and academic research, teaching and training, we open up organic-walled dinoflagellate cysts for the academic era of open science. We expect that palsys.org represents a starting point to improve taxonomic concepts, and we invite the community to contribute.

The ANDRILL SMS site provides the first Middle Miocene Antarctic fungal record. The CREST plant-based paleoclimate reconstructions confirm an intensification of the hydrological cycle during the MCO, with the Ross Sea region reconstructed 279 % wetter than modern conditions and a maximum mean annual temperature of 10.3 °C for the warmest intervals of the MCO. The plant-based reconstructions indicate a temperate, no dry season with a warm summer (Cfb) Köppen–Geiger climate classification.

The pollen and dinoflagellate cyst content of 21 surface sediments from the northern Gulf of Mexico is used to test the applicability of three palynological ratios (heterotroph/autotroph, pollen/dinocyst, and pollen/bisaccate ratio) as proxies for marine productivity and distance to the coast/river. Redundancy analysis confirms the suitability of these three ratios, where the H/A ratio can be used as an indicator of primary production, and the P/B ratio best tracks the distance to the coast.

Dinoflagellate cysts can be used to infer past oceanographic conditions in the Southern Ocean. This requires knowledge of their present-day ecologic affinities. We add 66 Antarctic-proximal surface sediment samples to the Southern Ocean data and derive oceanographic conditions at those stations. Dinoflagellate cysts are clearly biogeographically separated along latitudinal gradients of temperature, sea ice, nutrients, and salinity, which allows us to reconstruct these parameters for the past.

We use marine microfossil (dinocyst) assemblage data as well as seismic and tectonic investigations to reconstruct the oceanographic history south of Australia 37–20 Ma as the Tasmanian Gateway widens and deepens. Our results show stable conditions with typically warmer dinocysts south of Australia, which contrasts with the colder dinocysts closer to Antarctica, indicating the establishment of modern oceanographic conditions with a strong Southern Ocean temperature gradient and frontal systems.

This paper describes a new species of the genus Desmocysta from the Late Cretaceous in the Norwegian Sea. The short stratigraphic range for this new species makes it a good biostratigraphic marker. The available published data also indicate that this genus is restricted to higher latitudes in the Northern Hemisphere and is suggested to have preferred turbid waters and stressed marine environments.

New high-resolution microfossil record from a clay succession in the US Gulf Coastal Plain reveal more accurate age estimates for the critical Eocene–Oligocene transition (EOT), a global climate event marked by the rapid expansion of the first permanent Antarctic ice sheet 34 million years ago. These data suggest a coeval major increase in sedimentation rate. Future isotopic and palaeoecological work on this core can be more precisely integrated with other global records of the EOT.

Many major food crops, including rice, wheat, maize, rye, barley, oats and millet, are domesticated species of grass. However, because grass pollen all looks highly similar, it has been challenging to track grass domestication using pollen in archaeological samples. Here, we show that we can use the chemical signature of pollen grains to classify different grass species. This approach has the potential to help unravel the spread of domestication and agriculture over the last 10 000 years.

Morphology of dinoflagellate cysts (which are valuable tools in deciphering past environmental and climate changes) depends not only on genetics, but also on a range of environmental factors. We review frequently occurring (Black Sea) morphotypes and propose use of matrices to record gradual variation between endmember forms as a pragmatic approach until cyst–theca studies and genetic sequencing can demonstrate relationships between genetically and environmentally controlled morphotypes.

We present an extensive overview of the organic microfossil remains found at Site U1357, Adélie Basin, East Antarctica. The organic microfossil remains are exceptionally well preserved and are derived from unicellular as well as higher organisms. We provide a morphological description, photographic images, and a discussion of the ecological preferences of the biological species from which the organic remains were derived.

Short summary
In order to use ocean sediments as a recorder of past oceanographic changes, a critical first step is to stratigraphically date the sediments. The absence of microfossils with known stratigraphic ranges has always hindered dating of Southern Ocean sediments. Here we tie dinocyst ranges to the international timescale in a well-dated sediment core from offshore Antarctica. With this, we can now use dinocysts as a biostratigraphic tool in otherwise stratigraphically poorly dated sediments.

Short summary
We described two new species of the fossil dinoflagellate cyst genus Svalbardella. S. clausii sp. nov. has a narrow range in the lowermost Chattian and may be related to cooler surface waters. S. kareniae sp. nov. ranges from Lower Oligocene to Lower Miocene and favours more open marine conditions.
Our study illustrates the close phylogenetic relationship between Svalbardella and Palaeocystodinium and shows that surface ornamentation and the tabulation are variable features within both genera.
