Nannoplankton Congress (INA 19) in Llandudno (Wales)
The 19 International Nannoplankton Association Congress took place on the coastal city of Llandudno (Wales) from September 9 until 13, 2024.
The Ceratoliths are a type of calcareous nannoplankton which allow to subdivided the Messinian and the Pliocene stages. A series of works by Carlos Lancis, José Enrique Tent-Manclús and José-Abel Flores, comparing Light Microscope and Scan Electronic Microscope image, have redefined the Messinian and Pliocene Ceratolithaceae Family and its unrevail its phylogenetic evolution.
Three works published in the Journal of Nannoplankton Research (JNR) abstract volume (here):

Alicante 2024 Thinkinazul meeting
Last june 11th to 13th 2024 in the Universidad de Alicante facilities took place the third meeting of the of the Valencian Comunity Thinkinazul project.
The meeting was in the Alfredo Orts degrees room. Below a picture of some of the attendents.
ROV driving experience
Students in the third year of the Geology Degree of the course “Geophysics and geophysical prospecting”, under the supervision of Professor José Enrique Tent Manclús, carried out practices in the University of Alicante Ducks pond to learn how to drive a ROV. The picture show some students trying to understand the ROV commands (left).
marine geophysics on board a ship
Last February 15th, 2023, students in the third year of the Geology Degree of the course “Geophysics and geophysical prospecting”, under the supervision of Professor José Enrique Tent Manclús, carried out practices aboard the “Rosa de Abril” boat from the Alicante harbor. The practice was show a Boomer High resolution reflexion equipment and a ROV. The picture show a student trying to understand the ROV commands.
Origin and evolution of the Neogene calcareous nannofossil Ceratolithus
Sediment samples of deep marine oceanic ODP boreholes from sites 999 in the Caribbean Sea and 1237 in the Eastern Pacific Ocean covering the period between 6 and 4.5 Ma have been studied with a focus on ceratolith evolution. Orthorhabdus rugosus is a nannolith with three blades (sinistral, median, and dextral) that first appeared during the Serravallian, it is not-birefringent in its stable orientation. It shows a high morphological variability time-interval at the end of the Messinian to the basal Pliocene (5.5 to 5 Ma) during which Ceratolithus (5.484 Ma) evolved. Changes occurred in the sinistral and median blades, whilst the dextral blade was reduced. Ceratolithus finifer n. comb is the first species of the evolutionary line. The nannolith stable position changed during its evolution, resulting in the older forms showing low birefringence and the younger ones moderate to high birefringence in the most stable orientation. Ceratolithus acutus, with an arrowhead shape, Ceratolithus armatus, and the morphologically distinct C. larrymayeri evolved from C. finifer with all three species showing high birefringence. The previous O. rugosus and C. finifer continued. Finally, C. armatus gives rise to C. cristatus. Ceratolithus atlanticus and C. tricorniculatus also evolved from C. finifer. All the species mentioned become extinct during the Pliocene except Ceratolithus cristatus that lives today. Detailed observations permit the analysis of the evolutionary trends of the group, possible mechanisms, patterns, and processes of speciation, and establish new criteria to define the species that, by their relative abundance and short geologic range, have permitted adjustment of biostratigraphic markers for this period.

Sorbas field trip Alicante Marine Sciences 2023
This year the students of the third course of Marine sciences of the Alicante University visit the Mesa de Rodan, Cabo de Gata, and Sorbas basin on November 2nd and 3th of 2023.
The picture show the student visiting the Sorbas gypsum karst (Almeria).
The professors of the subject were Antonio Estévez, Manuel Martín-Martín, David Bonomo, and José Enrique Tent-Manclús.
Best article in the field of marine technology and renewable energy in the Martech workshop
Award for the best article in the field of marine technology and renewable energy sponsored by Nautilus Oceanica at the Martech 2023 congress, Tenth international workshop on marine technology, Jaume I University, Castellón de la Plana. For the article entitled: “Low cost USV development to study spring ponds” by Ronda, J. L., Benabdeloued, B. Y. N. and Tent-Manclús, J. E. belonging to the Department of Earth and Environmental Sciences and the Seismic Network of the Valencian Community (SISCOVA).
The article deals with the development of a USV (Unmanned Surface Vehicle) a surface unmanned ship for the study of springs. It is a small remote-controlled vehicle with a control post, from where it is manned. It has two cameras, one underwater and one frontal, which transmit real-time GPS location, also in real time, and bathymetry probe sensors and side-scan Sonar.

MOLICO-CV a thinkinazul Project
The project will study changes in the coast-line, coastal risk and coastal aquifers, an its logo is:
The leadership of the project is carried out by researches of the MIES is a Multidisciplinary Research Institute for Environmental Studies “Ramón Margalef” (Instituto Multidisciplinario para el estudio del Medio “Ramon Margalef”, IMEM in Spanish) of the Alicante University and integrate researches of 10 universities and research institutions.
