Investigating the Anomalously Warm North Atlantic Ocean in Summer 2023
This is a suggestion for a Degree Project for Bachelor's and Master's levels at the Department of Marine Sciences. Degree projects at the Department of Marine Sciences are done independently and must be written and assessed individually.
Subject: Oceanography
Level: Bachelor's (15hp) or Master's (45-60 hp) thesis project
Location: Gothenburg
Supervisor: Fabien Roquet
Project background
The unprecedented warmth observed in the North Atlantic Ocean during the summer of 2023 has raised significant questions about its causes, impacts, and potential future trends.
This project aims to investigate the anomalous sea surface temperature (SST) conditions through a combination of observational data analysis and model reanalysis techniques.
Project description
The primary objective of this project is to understand the drivers and mechanisms behind the exceptionally warm North Atlantic Ocean during the summer of 2023, and which continued until spring 2024 (at least).
Specifically, the project will focus on elucidating the role of atmospheric circulation patterns (NAO, ENSO…), ocean dynamics, and potential long-term climate trends in shaping these anomalous conditions.
The methodology involves gathering observational data sets, including satellite-derived sea surface temperature (SST) data, atmospheric forcing data, and oceanographic measurements, to analyze the spatiotemporal evolution of SST anomalies in the North Atlantic before and during the summer.
Additionally, model reanalysis products (GLORYS) will be used to obtain a more comprehensive picture of the subsurface ocean response.
Skills
- Study the atmospheric and oceanic processes driving SST anomalies.
- Analyze satellite and model reanalysis products to extract knowledge.
- Learn how to use a scientific programming tool for ocean data analysis.
