TITLE
High resolution 4-dimensional coherent sampling with autonomous moored profilers.
ABSTRACT
One of the grand challenges in building coastal environmental sensing networks is to develop in situ systems that can provide to the network data on the vertical and horizontal spatial and temporal variability in the physical, biological, and chemical structure of the coastal ocean.
In order to meet this challenge, we have developed and field tested an autonomous moored profiler. Herein we describe a totally self-contained, easily re-locatable autonomous profiler technology that can be rapidly
deployed in the coastal ocean and used to collect vertical profiles of physical, chemical and biological structure which are radioed to a network at the end of each cast.
This technology has evolved from a highly specialized prototype version designed for scientific studies of thin layer dynamics (referred to as the ORCAS profiler) into a commercial version (WET Labs MiniAMP) designed to meet broader community needs for monitoring the coastal ocean.
Field deployments of a 3D array of the ORCAS profilers during ONR's Layered Organization of the Coastal Ocean experiment have demonstrated that data from these systems cannot only quantify the temporal and spatial variation in finescale physical, optical, chemical and biological structure need for quantifying patchiness, understanding systems dynamics and testing models, but it can also provide the near-real-time data needed to detect episodic events (such as hypoxia, thin layers, anoxia, and harmful algal blooms) and guide sampling of those events from ships or AUVs.
The design and results of initial field tests of the MiniAMP profilers will be presented and discussed in the context of building coastal environmental sensing networks.
The CMOP seminar/lecture series aims to inform and educate the participants, give specific direction for future CMOP research, and bring together researchers and others in the community in order to develop professional relationships.
We invite all who are interested to attend.
