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 - Sri Kalyan Tangirala - «Injection protocols are more important than we think in hydraulic stimulation of enhanced geothermal systems (EGS)»
  Asbtract Geothermal energy is the cleanest and the most reliable source of renewable energy when compared to other options like solar or wind. From lighting up 5 bulbs in Italy in 1904, electricity generation from geothermal energy sources has come a long way to a total capacity of 16,355 MW (0.5% of total) by the end of 2023, most of which coming from hydrothermal reservoirs. In order to accelerate the scaling of electricity generation, Enhanced Geothermal Systems (EGS) in non-volcanic areas need to be developed. Creating these EGS requires enhancing the permeability of natural fractures through a process called hydraulic stimulation. A natural outcome of this process is microseismicity (usually Mw<2), but in a few occasions, there have been earthquakes of greater magnitude (e.g., Mw 3.4 and Mw 5.5 at Basel (Switzerland) and Pohang (Korea Republic), respectively) which were very disturbing and ended up with project cancellation. Hydraulic stimulation operations are usually designed making use of a scaling law which states that the maximum magnitude of induced earthquakes is linearly proportional to the total volume of water injected into the system. Our numerical studies on hydraulic stimulation in EGS show that the injection protocol has a stronger contribution to the maximum magnitude earthquake over the total volume of injected water.

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.
