Nine months into the four year £2 million Engineering and Physical Sciences Research Council (EPSRC) and Natural Environment Research Council (NERC) funded project, Professor Hywel Morgan from the University's School of Electronics and Computer Science and Matt Mowlem at the National Oceanography Centre, Southampton, have developed the first of a new generation of miniaturised sensors to measure marine environments and tested them at depths of 1600 metres.
'These sensors were dropped into the water strapped to a device which measures the temperature and salinity of the oceans as a function of depth, and the sensors measured the nitrate and nitrite concentrations, which are important characteristics of ocean chemistry. Phosphate, iron and manganese can also be measured with this technology,’ said Professor Morgan.
Now that the researchers have established that the sensors are capable of measuring harsh environments, they will develop them further so that they can be deployed for months at a time.
'This first generation of sensor systems as they stand are about the size of a large drinks bottle,’ Professor Morgan added. ‘We aim to make them much smaller so that they are capable of operating remotely without bulky, expensive and power hungry support systems.’
The project has two strands: to develop lab-on-a-chip chemical and biochemical analysers to detect nutrients and pollutants at the ultra low concentrations found in the ocean, and to develop small chips to identify individual phytoplankton in the oceans. The development of these biogeochemical sensors over the next three years will provide a new technology platform for marine scientists, and have applications in many allied activities such as those undertaken by the water industry, in environmental impact assessments and in monitoring ship ballast water.
‘We believe that the development of micro-sensing systems that will be utilised across the broad front in marine sensing will be a world first,’ said Dr Mowlem.

A new indicator for marine ecosystem changes: the diatom/dinoflagellate index

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
