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.

Internal Cycle of Seminars IMEDEA - Fiona Tomas-Nash - «Sex or no sex under stress? Unprecedented widespread unique reproductive behaviour of the seagrass Posidonia oceanica after a marine heat wave»



Warming can have dramatic effects on plant phenology and reproduction, with important consequences for reproductive output, plant survivorship, or species dispersal. In seagrasses, vegetative growth through clonal expansion is generally the dominant strategy for meadow maintenance, expansion and recovery, with sexual reproduction strongly differing amongst species, being rare for some, and some times associated with disturbance. Even rarer is the occurrence of pseudovivipary, an uncommon phenomenon in the plant realm, which has only been reported twice before in the marine environment as highly localized phenomena associated with environmental stress. Pseudovivipary is an asexual reproduction strategy whereby plantlets replace sexual reproductive structures, leading to the maintenance of the maternal clones. In summer of 2022, the Mediterranean Sea underwent unprecedented warming, and, associated with it, we observed extensive flowering (100% of sites) as well as pseudovivipary across numerous (>85 % of 36 sites) Posidonia oceanica meadows along the Balearic Islands. Our results support the notion that P. oceanica flowering is triggered under high warming but also, and importantly, this is the first time ever that pseudovivipary is reported across so many locations in a marine plant, and the fate of these plantlets is being monitored by assessing development, survivorship and dispersal through time. Considering the negative impacts that warming can have on seagrass ecosystems, the discovery of widespread pseudovivipary is a critical aspect to consider for understanding mechanisms of resilience in seagrasses.
