Deep learning in the marine sciences

Developing models and application to monitor the environment and climate.

Ecological studies involving e.g. classification and statistical counting of species in an ecosystem has been a challenging and time consuming task in the marine sciences. Deep learning has the potential to automate and streamline the steps required in such studies, but few applications in this domain has been developed.

An important source of data in marine sciences is the echo sounder which is used to observe the marine ecosystem at a larger scale. Some preliminary approaches using convolutional neural networks (CNNs) for fish detection and classification from acoustic data are emerging.

Many of the challenges related to the use of deep learning in this area are related to training data, where the amount of annotations can be limited and the quality variable and it is too expensive to get more and/or better data. There is also a need for explainability and reliability, as trust becomes very important when the output from these systems are intended as input to models for abundance estimation which again is a basis for setting of fishing quotas.

Visual Intelligence are advancing deep learning in the marine sciences to overcome these challenges.
