Analysis of nifH gene diversity from four Arctic regions (rivers, seawater and sediment traps) during 2014 and 2019

To investigate the effects of concurrent environmental change and heatwaves, we performed an incubation experiment in the mesocosm facility of the Alfred Wegener Institute on...

The goal of this study is to reveal dynamics of prokaryotic viruses following shifts in abundant prokaryotes during marine phytoplanktonic blooms. To this end, a microcosm...

A large fraction of the organic matter fixed in the oceans is transformed and remineralised by marine heterotrophic microorganisms. They, therefore, play a critical role in the...

Several depths of the full water column of two stations (HGIV and N4) were sequenced in order to correlate the communities of the Fram Strait water column at HAUSGARTEN with...

To explore the phytoplankton communities, the metabarcoding analysis using v4 region of 18S rDNA were conducted.

Samples were collected during the Polarstern cruise PS112 between March and May 2018 along the western Antarctic Peninsula in the Southern Ocean. Genomic DNA was isolated from...

Pseudo-nitzschia spp. produces a neurotoxin, domoic acid (DA), which can cause illness in humans, commonly known as amnesic shellfish poisoning, mass-mortality of marine...

Samples were collected from the underway seawater system of the german research vessel Polarstern during the PS113 expedition 2018. The dataset is comprised of primary...

Shotgun metagenomic data and 16S rRNA gene sequence amplicon data from latrunculid sponges primarily collected off the South African coast (Collection includes 3 Latrunculia sp....

22 environmental metagenomic surface water (20 m depth) samples from two transects to the Southern and Atlantic Ocean (RV Polarstern ANT-XXVIII/4 and ANT-XXVIII/5 in 2012)....

We compared the prey community of Antarctic krill retrieved from the 18S regions V4 and V7 and assessed the effect of different processing procedures on the prey community of...

18S rDNA V4 region of environmental samples from Jiaozhu Bay Raw sequence reads

Investigation of the field transcriptome of the calanoid copepod Calanus finmarchicus (Crustacea) during the Arctic Midnight Sun, using RNA sequencing. CV stage individuals were...

Mesoscale eddies contribute to the distribution of resources for plankton to thrive but can also trap and isolate plankton communities resulting in rapidly vanishing resources....

Water samples were taken at three different locations in the German Bight: Cuxhaven, Wilhelmshaven and Helgoland. These samples were sequenced on a Illumina Miseq in order to...

Metabarcoding analysis of phytoplankton compositions in the North China Sea

Polar winter waters are one of the least studied marine ecosystems with regard to microbial life and Thaumarchaeota are key microorganisms in this environment. We collected data...

The16SrRNA gene data are amplicon sequences PCR amplified with the primers 341_ill forward (TCGTCGGCAGATGTGTATAAGAGACAGCCTACGGGNGGCWGCAG) and 802_ill reverse...

In the present study, with the aim of understanding the effects of the gigantic earthquake and its resulting tsunami in Tohoku area on marine biodiversity and ecosystem, we...
