PEGASO Cruise, Antarctica.

In early 2015 I was fornutante to participate in the Antartic Cruise PEGASO (Plankton-derived Emission of trace Gases and Aerosols in the Southern Ocean) aboard the R/V Hespérides lead by Dr. Rafel Simó, ICM-CSIC.  The PEGASO project aims to fill crucial knowledge gaps presently existing in the timely subject of marine aerosol sources as well as the main aerosol chemical, physical and biological processes responsible for aerosol formation and transformation in open ocean regions. Aerosols, depending on their properties, can dramatically alter clouds, either increasing or decreasing the sun-reflecting effect.


Tara Oceans Expedition

Between 2009 and 2012 the international Tara Oceans Expedition took place aboard the schooner Tara which circumnavigated the world oceans to explore the diversity, evolution and ecology of all compartments of plankton including viruses, bacteria, archaea, protists, metazoans, and even fish larvae. I was fortunate to participate in the planning and organization of this expedition and to sail in different legs including the Red Sea or the Sargasso Sea.


Station ALOHA, Hawaii

In 2010 I participated in a cruise lead by Dr. Ben van Mooy at the oceanographic Station ALOHA north of the island of Oahu in the Hawaii Archipelago. ALOHA is a station where several oceanographic studies have been conducted since its stablishment in 1988 with the intend to understand and explain the dynamics of the greater North Pacific Ocean. This cruise was carried out on the R/V Kilo Moana from the University of Hawaii. There, Dr. Michal Koblizek and I work in studying the growth rates and responses to nutrient limitation of marine photoheterotrophic bacteria.


Gulf of Lion, NW Mediterranean

In 2009, three cruises lead by Dr. Mikel Latasa were conducted in the Gulf of Lion (NW Mediterranean) aboard the R/V Sarmiento de Gamboa in order to study the fate of the northwestern Mediterranean open sea spring bloom. During these cruises, I studied the bacterioplankton community that accompanies the phytoplankton bloom that yearly occurs  in this area.


Deep-Sea Hydrothermal Vents

During my postdoc at the Reysenbach Lab at Portland State University, I participated in two research cruises aboard the R/V Atlantis from Woods Hole Oceanographic Institution. The main goal of these cruises led by Dr. Karen von Damm was to elucidate the ties between temporal variations in hydrothermal fluid chemistry to crustal and biological processes at 9-10N East Pacific Rise. In particular, the team from Portland were interested in studying how the geochemistry of hydrothermal fluids influences the diversity and distribution of thermophilic microorganisms. During these cruises which took place in 2006 and 2007 I had the amazing experience of diving in the Deep Submergene Vehicle Alvin.


Yellowstone National Park, USA.

During my postdoc at the Reysenbach Lab at Portland State University, we did various sampling trips to Yellowstone National Park with the main purpose of studying the Aquificales, a group of thermophilic bacteria that are widespread in terrestrial hot springs and deep-sea vents.
