GIS Seminar: Geospatial AI for Beehive Health

Dear All,

 

We are excited to continue our monthly seminar series on geospatial methods, and we invite you to join us for the next talk in the series. This month, we will feature a presentation by Julien Vadnais, a new PhD candidate who will present the findings from his master thesis.  His work focuses on the use of geospatial AI to predict the health of honey bee colonies in various landscapes:

 

Talk TitleApplications of geospatial artificial intelligence and big data to assess the effects of landscape on beehives' health

 

Abstract:
Honey bees play a critical role in ecosystems, but in recent years, colony mortality rates have been on the rise. This presentation will explore how geospatial data and machine learning can be used to predict beehive health across different landscapes. Coupling a unique dataset comprising georeferenced health reports on 6,704 colonies in the province of Quebec, Canada, with various remote sensing products, we computed landscape metrics at multiple scales and ran a Random Survival Forests (RSF) model to predict the lifespan of colonies in various landscape scenarios.

Date: Wednesday 9th of October 13:00 
Location: Kvartsitten (3rd floor of Realfagbygget opposite the mammoth)
Speaker: Julien Vadnais, Department of Earth Science, UiB

 

Call for Speakers
If you are interested in presenting your geospatial work or know of an external speaker who would be a good fit for our seminar series, please get in touch! We have funding available for three external guest speakers to visit Bergen this semester.

 

We look forward to seeing you there!

 

Ben, Suzette, Dan, Elise

Seminar: Current Trends of Oceanic Variability in Regional Simulation Of The Greater Agulhas Current System & Projected Changes In Climate Models

Dear all,

This Friday at 13:15-14:00 Dr. Issufo Halo, one of this years Bjerknes Visting Fellows, will give a seminar.

 

Dr Issufo Halo is visiting from 22. October to 2. November.  He is a scientist based at DFFE (Department of Forestry, Fisheries and the Environment, Cape Town, South Africa), his scientific expertise focuses on ocean dynamics in the greater Agulhas Current system and with specialisation on interaction between large-scale currents and mesoscale processes.

 

The overall goal of the visit is to establish future scientific research collaboration between scientists from the Bjerknes Centre and the South African Department of Forestry, Fisheries and the Environmental, to foster a better understanding of the ocean dynamics in the Agulhas Current system, and address questions of future climate projections in the region. 

 

If you want to meet him while he is visiting, please contact Annette Samuelsen (annette.samuelsen@nersc.no).

BCCR Seminar: "Barotropic Trends through Barents Sea Opening for the period 1975-2022, The Underlying Physical Processes explained using Artificial Intelligence"

Drear all!

We will have a BCCR Seminar on Tuesday 29.10.2024. Robinson Hordoir from IMR and Vahidreza Jahanmard from Tallinn University of Technology will give a talk titled "Barotropic Trends through Barents Sea Opening for the period 1975-2022, The Underlying Physical Processes explained using Artificial Intelligence". The seminar will start at 14:15 in room 4020 as usual, and coffee and biscuits will be served. Well met! 

 

Abstract

Climate models and observations show that the flow from the Nordic Seas to the Barents Sea, through Barents Sea Opening increased during the period 1975-2022, contributing to the « Arctic Atlantification » process. However, the underlying physical reasons behind this trend are still unexplained.

Using Artificial Intelligence, we reconstructed the barotropic flow at Barents Sea Opening, based on wind data over the Nordic Seas. The constraints required to perform this reconstruction provide the first hints on the nature of the trends, which we find to be linked with high frequency processes. This relation is confirmed through sensitivity experiments, as it appears that the Barents Sea Opening flow trend can not be explained by a linear wind trend, nor through a trend in the main wind variability modes. We therefore orientate our research towards a non-linear explanation. Using a second version of a deep learning model on one hand, and idealized 3D ocean modelling simulations on the other hand, we identify the underlying physical processes that explain the Barents Sea Opening flow trend through spectral sensitivity experiments.

 

About the speakers

Robinson Hordoir is a researcher at the Institute of Marine Research, and the Bjerknes Centre for Climate Research. He specializes in ocean modelling and physical oceanography, and is interested in ocean processes, and changes in ocean processes. He develops regional ocean models based on the NEMO ocean engine, which are used for hindcast and climate downscaling simulations.

 

Vahidreza Jahanmard is a researcher in the department of Building and Civil Engineering and Architecture of Tallinn University of Technology. His work focuses on the application of machine learning techniques for integrating sea level data sources and forecasting absolute dynamic topography. He is also collaborating with the IMR to develop causal deep learning model aimed at identifying and understanding the drivers of the flow trend in the Barents Sea Opening.
