IS51A:
Recent Advances in In Situ Biogeochemical Instrumentation, Sensors, and Observatory Science I


Session ID#: 9932

Session Description:
Complex interactions of physical, biological, and chemical parameters
affect aquatic biogeochemical cycling over a wide range of spatial and
temporal scales, making observations of marine ecosystems particularly
challenging.  Development and deployment of in-situ technologies to
measure these parameters have thus been widely recognized as a research
priority in the oceanographic community, to both improve scientific
understanding and inform management and policy decisions governing these
historical “undersampled” regions.  As advances are made in development
of in-situ sensors and instrumentation, it is critical to share both
successes and challenges across the community; as such, this
interdisciplinary session is targeted at both scientists and engineers
to facilitate accelerated improvement of the next generation of sensors
and instrumentation technologies, data analysis techniques applied to
high-resolution sensor data, and calibration/validation mechanisms.
Topics may include:  (1) adaptation of traditional instrumentation for
field use, i.e., “field hardening,” (2) development of novel in-situ
hardware (new techniques or new targets), (3) new deployment or
operation techniques that improve data quality (online calibration,
reduced energy consumption, reduced biofouling), (4) cost-lowering
techniques, (5) data analysis, data quality, or data distribution
improvements, or (6) lessons learned from existing deployments that
provide guidance for improvements in hardware and/or software methods.
This session would be an ideal candidate to include hardware or software
tutorials.
