IEOOS, the Spanish Institute of Oceanography integrated ocean Observing System

Since its foundation, 100 years ago, the Spanish Institute of Oceanography (IEO) has been observing and measuring the ocean characteristics. Some systems like the tide gauges network has been working for more than 60 years. The IEO standard sections began at different moments depending on the local projects, and nowadays there are XXX coastal stations and XXX deep ones that are systematically sampled, taking physical as well as biochemical measurements. At this moment, the IEO Observing System (IEOOS) includes 4 permanent moorings equipped with currentmeters, an open-sea ocean-meteorological buoy offshore Santander and an SST satellital image reception station. It also supports the Spanish contribution to the ARGO international program with 47 deployed profilers, and continuous monitoring thermosalinometers, meteorological stations and ADCP installed on the IEO research vessels. All these networks are linked to international iniciatives like SeaDataNet, Emodnet, IbiROOS and MONGOOS. The system is completed with the IEO contribution to the RAIA and Gibraltar observatories, and the development of regional prediction models. All these systematic measurements allow IEO to give responses to ocean research activities, official agencies requirements and industrial and main society demands

Amorphous microporous molecular sieves studied by laser-polarized 129Xe NMR spectroscopy

International audienceCrystalline zeolites, ZSM-12 and ITQ-21, and their amorphous precursors presenting the same porosity, have been studied by hyperpolarized 129Xe NMR spectroscopy of adsorbed Xe. The higher chemical shifts and the smaller chemical shift variations with Xe concentration observed for the amorphous compared to the crystalline materials show that the pores exhibit a surface roughness responsible for a stronger Xe-surface interaction that occurs at the expense of Xe-Xe interaction inside the micropores
