Sampling in Ísafjarðardjúp, North West Iceland. In addition to oceanographic measurements and plankton surveys, we're isolating environmental DNA at key location near and far from aquaculture pens.
Gullfallegur dagur til að hefja leiðangur. Sem partur af "Ástand Sjávar" vorleiðangri sem stendur yfir næstu tvær vikur, munum við taka sýni til að meta sviðþörungsblóma, þróa umhverfis DNA vöktunaraðferðir í kringum sjókvíar, og auðvitað safna aragrúa af haffræðilegum mælingum

Funding from the project came from Running Tide, which operated in Iceland from 2022 until it went bankrupt in 2024. In total 52 whole Saccharina latissima genomes were generated and they are publicly available here: trace.ncbi.nlm.nih.gov/Traces/study...

Sæfluga (Clione limacina) - skel laus sæsnigill, sem kom í háf rétt norðan við Reykjafjarðarál.
Þessir sniglar fljúga um í sjónum og nota sérstök stöðuskynfæri sem innihalda stöðusteina til þess að vita í hvaða átt þau snúa, dálítið eins og innra eyra okkar.

Beautiful day for the start of an expedition. As part of the "State of the Sea" (Ástand Sjávar) survey over the next two weeks, we'll be sampling to predict algal blooms, develop eDNA monitoring around aquaculture pens, and take oceanographic measurements all around Iceland

Our new article on sugar kelp genomics across western Iceland is now out. We find substructure across a North-South and inner- to outer-bay gradient. SNP association with key environmental variables suggest local adaptation and/or density dependent selection is having an effect.

Interestingly, aragonite saturation was the key environmental factor which explained allelic turnover in a Gradient Forest analysis. This is an environmental factor which is impacted by the density of sugar kelp, and could suggest density dependent substructure across this range.

📦 My new R package {spatialData} is on CRAN! 🎉
Ecological datasets as sf data frames and their companion raster data ready for analysis and modeling.
Built as example data for R packages, but great for teaching too!
🔗 blasbenito.github.io/spatialData/
❗check the Articles section!
Provides spatial datasets ready to use for ecological modelling and raster companion data for prediction: Neanderthal presence during the Last Interglacial (Benito et al. 2017 <doi:10.1111/jbi.12845>)...
U.S. President Donald Trump has fired all 24 members of the National Science Board, the body that oversees the National Science Foundation. https://scim.ag/4cxQWhl
Dismissal of the National Science Board is widely seen as latest move to erase NSF’s independence
