Internal Cycle of Seminars at IMEDEA (CISI) consist on a cycle of seminar presentations given mainly by doctoral students, masters and junior postdocs, although it is not closed to other staff, such as visitors and staff, that take place every Friday from 4:00 p.m. to 4:30 p.m in the seminar room os IMEDEA.

This represents a great opportunity to learn more about the research carried out at the Institute and to bring those with less experience , the chance of increasing their presentation and public speaking skills. Afterwards, there will be soft drinks and beers for all attendees 😉 We strongly encourage you to participate. Join us!

Internal Cycle of Seminars IMEDEA - Amaya Álvarez- «Deep Learning inside the fish market»
  Abstract In this presentation, we will explore the various tasks undertaken by the Fish Ecology Lab at the Palma Fish Market since 2018. Our focus lies in automating the processes employed for extracting fish length measurements. The dynamic distribution of fish lengths plays a crucial role, not only in making informed short-term operational decisions within a fishery co-management framework but also in providing input for traditional fishery models that illuminate mid- and long-term trends in exploited stocks. Traditionally, the estimation of fish length in most fisheries has been a manual endeavor, resulting in precise measurements at the individual fish level. However, due to the high cost and inefficiency associated with supervised sampling, the sample size tends to be limited. Consequently, the precision of population-level estimates often falls short, and biases may arise, especially when adequately stratified sampling programs are economically unfeasible. Conversely, the application of machine learning and artificial intelligence in fisheries science presents a promising avenue for large-scale, unbiased sampling of fish catches. The Fish Ecology Lab has been working with the daily images recived from the auction of the fish market to extract information on various commercial species such as hake, dolphinfish, and red shrimp. This presentation will specifically focus into the deep learning techniques employed for each of these cases.

Internal Cycle of Seminars IMEDEA - Pau Luque - «Use of a Continuous-Wave Radar to Estimate the Ocean Wave Spectra near the Coast.»



Monitoring hydrodynamic and morphological features in coastal areas, as well as their evolution, is a key task to support coastal management, of upmost importance in the current context of sea-level rise. In-situ sampling is commonly used to monitor the nearshore; however, they are time-consuming, spatially-limited and scarce, especially during large wave or strong current events. In contrast, remote sensing measurements are able to estimate hydrodynamics and morphology at higher sampling rates and over broader coastal areas. However, some remote sensing technologies, like satellite, and video cameras, are not able to measure continuously, as opposed to shore-based X-band radars. Pulsed radar has been used for this purpose over 20 years now, but continuous wave radars, which are safer and cheaper than their pulsed counterpart, have been virtually unexplored for this purpose. In this talk I will present our current work on the adaptation of a continuous X-band radar system to measure ocean wave spectra, aiming to complement and improve video camera systems for nearshore monitoring.
