Sea level is traditionally observed with tide gauges (TG). These measurements are relative to the Earth’s crust. To improve the understanding of sea level changes it is necessary to perform measurements with respect to the Earth’s center of mass. This can be done with satellite techniques. Global Navigation Satellite System (GNSS) is a tool that can solves several hundred kilometers vectors wit...

Benzothiazole (BT) is a natural and synthetic compound occurring in aquatic sediments and wastewater. The purpose of this work was to investigate BT biogeochemistry in controlled Eh/pH microcosms (CEPMs) containing estuarine sediments of different particle sizes (coarse, intermediate, fine) under oxidized and reduced conditions vs. killed controls, and tide simulation mesocosms (TSMs) containin...

Devolution The BMJ held a one-day conference in Glasgow on 3 April. The participants, from England, Scotland, and Wales, discussed whether they would like the Health Service in each country to devolve and the probable effects of the Government's White Paper on devolution-Our Changing Democracy: Devolution to Scotland and Wales. By invitation three of the participants prepared working papers whi...

Concurrent Level-3 data products from MERIS, MODIS, and SeaWiFS between June 2003 and June 2006 for the East China Seas were compared against each other to evaluate the consistency between the sensors. The atmospheres in these regions is generally turbid, with typical aerosol optical thickness at 865 nm (tau_865) around 0.16, therefore presents a challenge to atmospheric correction. The statist...

Noctiluca scintillans was seasonally abundant during the austral spring and summer with typical values of 16 cells l–1, but depleted in autumn and winter, with values of <1 cell l–1. Peaks in abundance of up to 79 cells l–1 were observed, at the same time or subsequent to diatom blooms which were caused by episodic uplifting events during the spring and summer. The diatom blooms were dominated ...

There is a critical need to simply and reliably monitor brevetoxins routinely in the blood of humans and aquatic animals. We used striped mullet as laboratory test animals to better define the uptake and elimination kinetics of brevetoxin during an aqueous exposure to the brevetoxin-producing dinoflagellate Karenia brevis. Striped mullet were first exposed to sublethal densities of K. brevis (a...
