Abstract

This storage will be connected to SNIC project SNIC2018-1-42, and a new large scale application for SNIC support (SNIC 2020/1-32). There are several computational projects that will benefit from the present storage. First we have a project (SNIC2018-1-42) on turbulence in tidal flows, and how an energy extracting device (Deep Green by company Minesto) interacts and produces turbulence. This project uses an (own) fortran code, and OpenFOAM. We have an PhD who just started and we foresee that he will increase the disk usage significantly on tertrailith during autumn. The disk space has been an issue for a long time but has become more acute lately. Two new EU projects (EU-2020 project EMERGE, and JPI-Ocean project FACTS) and a space board project (new) will require high resolution regional and coastal models for Skagerrak and Kattegatt, as well as very high resolution model for Öresund. Both these project aim at transport calculations of harmful substances (plastic and Persistant Aromatic Hydrocarbons). These models both generates significant output as well as requiring significant input from disk. This will rapidly increase the need for additional disk space. The storage project will also cover larger scale ocean dynamics using NEMO ocean model (EU project SO-CHIC and SNIC 2019/3-570). The main storage will be for a high resolution study of processes in the open ocean polynya (open water with an ice cover) in the ice around Antarctica. Large scale mixing processes and their relation to non-linear aspects of the density of water is also investigated using NEMO. The PI have, together with co-applicants, submitted a large scale application for a larger group of researches at Department of Marine Sciences at University of Gothenburg. This resource will be shared with persons in that application. However, if this new computational project is granted we foresee a significant increase of required disk space in autumn/winter. A new medium scale storage application will be submitted when required, but for now we expect a small-scale storage to be sufficient.
