Data on C:N:P of lab-cultured marine dinoflagellates were identified by searching in the ISI Web of Science using keywords such as elemental composition, elemental stoichiometry, elemental ratios, C:N, C:P or C:N combined with the word dinoflagellate. These studies and suitable studies cited within these sources were evaluated for data collection. Experimental conditions were recorded along with the elemental composition data including culturing methods, the media used, culture temperature and salinity. Cell volume and growth rate data were collected when available. Species were then assigned the following traits: 1. thecate or athecate; 2. non-toxic or the potential to produce C-rich or N-rich toxins; and 3. small, medium or large cell volume.

Average concentrations of benzene, NO2 and O3 in the air in Cartagena (Murcia, Spain) from 15 to 22 July 2009. Units are ug/m3.

Wood is a natural renewable material widely applied for construction, both interior and exterior. Because of being a material highly susceptible to degradation, coatings are often used for its protection. For the long-term performance, the wood-coating interface is of major interest as it determines e.g., the adhesion of the coatings. If the coating/wood interface fails, the coating will disintegrate within a short time and will blister, crack and peel. This failure can result in damage to the wood surface and in more costly and difficult refinishing. Coating adhesion is determined, among other factors, by its penetration through the wood interface. For the specific case of waterborne coatings, it is difficult to characterize their penetration by means of common techniques such as microscopies or tomographies as they do not typically fill the wood cell lumen. Instead, it is more likely that waterborne coatings penetrate the wood cell surfaces instead. At present, there is not a well-established methodology for these studies. We aim at proving with this experiment that Neutron Reflectometry is an optimal tool for these studies.

This dataset presents a collection of environmental measurements taken by the s-Nautilus profiler at "La Isleta" yacht club in the Mar Menor. The recorded variables include: -Time (yyyy-mm-dd hh:mm:ss): The timestamp indicating the date and time of each measurement. -Depth (m): The depth at which the measurements were taken. -Dissolved Oxygen (DO) : The concentration of dissolved oxygen, essential for assessing water quality and the health of the marine ecosystem. -Electrical Conductivity (EC): A parameter indicating the ability of the water to conduct electricity, directly related to salinity and the presence of ions. -Temperature (T) (ºC): The water temperature, a critical factor influencing many chemical and biological processes. -Battery Voltage (Batt3): The voltage of the batteries powering the electronics of the profiler, providing insight into its autonomy. Measurements were taken every 6 hours during the ascent of the profiler.
