Data for: Sedimentary ancient DNA and pollen reveal the composition of plant organic matter in Late Quaternary permafrost sediments of the Buor Khaya Peninsula (north-eastern Siberia)

Organic matter deposited in ancient, ice-rich permafrost sediments is vulnerable to climate change and may contribute to the future release of greenhouse gases; it is thus important to get a better characterization of the plant organic matter within such sediments. From a Late Quaternary permafrost sediment core from the Buor Khaya Peninsula, we analysed plant-derived sedimentary ancient DNA (sedaDNA) to identify the taxonomic composition of plant organic matter, and undertook palynological analysis to assess the environmental conditions during deposition. Using sedaDNA, we identified 154 taxa and from pollen and non-pollen palynomorphs we identified 83 taxa. In the deposits dated between 54 and 51 kyr BP, sedaDNA records a diverse low-centred polygon plant community including recurring aquatic pond vegetation while from the pollen record we infer terrestrial open-land vegetation with relatively dry environmental conditions at a regional scale. A fluctuating dominance of either terrestrial or swamp and aquatic taxa in both proxies allowed the local hydrological development of the polygon to be traced. In deposits dated between 11.4 and 9.7 kyr BP (13.4–11.1 cal kyr BP), sedaDNA shows a taxonomic turnover to moist shrub tundra and a lower taxonomic richness compared to the older samples. Pollen also records a shrub tundra community, mostly seen as changes in relative proportions of the most dominant taxa, while a decrease in taxonomic richness was less pronounced compared to sedaDNA. Our results show the advantages of using sedaDNA in combination with palynological analyses when macrofossils are rarely preserved. The high resolution of the sedaDNA record provides a detailed picture of the taxonomic composition of plant-derived organic matter throughout the core, and palynological analyses prove valuable by allowing for inferences of regional environmental conditions.

Photos and measurements of otoliths from fish caught in the southern part of the North Sea

Photos and measurements of otoliths from fish caught in the southern part of the North Sea is a photo dataset published by the <a href="https://www.inbo.be/en">Research Institute for Nature and Forest (INBO)</a>. It contains photos of fish otoliths – taken by a binocular microscope on a black background and edited to include a ruler – and measurement/reference data for these otoliths and fish. The dataset can be used as reference data to identify fish species in the southern part of the North Sea based on their otoliths, e.g. dietary/food ecology research of seabirds. Files <ul> <li>reference_data.csv: Fish information (scientific name, sampling information, length) and otolith measurements (width/height). Each row corresponds to a fish, which <code>fish_id</code> can be found in the otolith photo name.</li> <li>Scientific name.zip: Photos of otoliths, grouped by species. Photo names are of the form <code>fish_id_suffix.jpg</code>, where <code>suffix</code> indicates if it was a left (<code>Lx</code>) or right (<code>Rx</code>) sagittal otolith or a smaller lapillus/asteriscus (<code>Bx</code>) otolith.</li> </ul>

Reconstructed remote sensing land surface temperature data in North America in 2002-2018

In order to more accurately study the change trend of land surface temperature in North America in recent years, we combined remote sensing and meteorological station data and used various restoration models to generate more accurate and more complete remote sensing land surface temperature data. Our data covered the North American continent from 2002 to 2018, with a spatial resolution of 0.05°×0.05°. In order to facilitate the statistics of the data, we set the projection mode of the data as World_Cylindrical_Equal_Area. We collated the data from different time dimensions, including month, season and year.
