Dissolved oxygen probes: making oxygen measurements routine like temperature, St Petersburg, Florida, January 4-6, 2006: workshop proceedings

摘要

The Alliance for Coastal Technologies (ACT) Workshop "Making Oxygen MeasurementsudRoutine Like Temperature" was convened in St. Petersburg, Florida, January 4th - 6th, 2006. Thisudevent was sponsored by the University of South Florida (USF) College of Marine Science, anudACT partner institution and co-hosted by the Ocean Research Interactive Observatory Networksud(ORION). Participants from researcldacademia, resource management, industry, and engineeringudsectors collaborated with the aim to foster ideas and information on how to make measuringuddissolved oxygen a routine part of a coastal or open ocean observing system.udPlans are in motion to develop large scale ocean observing systems as part of the US IntegratedudOcean Observing System (100s; see http://ocean.us) and the NSF Ocean Observatory Initiativeud(001; see http://www.orionprogram.org/00I/default.hl). These systems will require biologicaludand chemical sensors that can be deployed in large numbers, with high reliability, and forudextended periods of time (years). It is also likely that the development cycle for new sensors isudsufficiently long enough that completely new instruments, which operate on novel principles,udcannot be developed before these complex observing systems will be deployed. The most likelyudpath to development of robust, reliable, high endurance sensors in the near future is to moveudthe current generation of sensors to a much greater degree of readiness. The ACT OxygenudSensor Technology Evaluation demonstrated two important facts that are related to the need forudsensors. There is a suite of commercially available sensors that can, in some circumstances,udgenerate high quality data; however, the evaluation also showed that none of the sensors were ableudto generate high quality data in all circumstances for even one month time periods due toudbiofouling issues.udMany groups are attempting to use oxygen sensors in large observing programs; however, thereudoften seems to be limited communication between these groups and they often do not have accessudto sophisticated engineering resources. Instrument manufacturers also do not have sufficientudresources to bring sensors, which are marketable, but of limited endurance or reliability, to audhigher state of readiness. The goal of this ACT/ORION Oxygen Sensor Workshop was to bringudtogether a group of experienced oceanographers who are now deploying oxygen sensors inudextended arrays along with a core of experienced and interested academic and industrialudengineers, and manufacturers. The intended direction for this workshop was for this group toudexchange information accumulated through a variety of sensor deployments, examine failureudmechanisms and explore a variety of potential solutions to these problems. One anticipatedudoutcome was for there to be focused recommendations to funding agencies on development needsudand potential solutions for 02 sensors. (pdf contains 19 pages)
