Biosensors for marine applications: We all need the sea, but does the sea need biosensors?

Abstract
The aim of the paper is to explain the rationale behind marine biosensor applications, give an overview of measurement strategies currently employed, summarise some of the relevant available biosensor technology as well as instrumentation requirements for marine sensors and attempt a forward look at what the future might hold in terms of needs and developments. Application areas considered are eutrophication, organism detection, food safety, pollutants, trace metals and ecotoxicology. The drivers for many of these studies are discussed and the policy environment for current and future measurements is outlined.

Comments
This paper describes the state of bionsensors in marine applications. Development of biosensors for marine applications lags behind other fields. Reasons: Difficult work environment, lesser payoffs. Discussion of the need for appropriate spatial and temporal resolution of data.  Biosensors for environmental stresses:  Eutrophication,  organism detection (plankton, fish eggs),  pesticides, drilling fluids, food safety (seafood algal toxins). Genetically modified bacteria unlikely to be used in the field due to the potential for uncontrolled release.
