Emerging marine observation technologies provide new opportunities to learn about phytoplankton communities with greater spatiotemporal resolution. Autonomous vehicles enable real-time ocean data collection and communications over long durations, in varying sea states and at lower cost than crewed ships. The Jupiter Research Foundation is developing a novel device to obtain near real-time phytoplankton...
The Oceans of Tomorrow (OoT) projects, funded by the European Commission's FP7 program, are developing a new generation of sensors supporting physical, biogeochemical and biological oceanographic monitoring. The sensors range from acoustic to optical fluorometers to labs on a chip. The result is that the outputs are diverse in a variety of formats and communication methodologies. The interfaces with...
Coastal upwelling brings cooler, saltier, and nutrient-rich deep water upward to the surface. Upwelling fronts support enriched phytoplankton and zooplankton populations, thus having great influences on ocean ecosystems. We have developed a method to enable a Wave Glider (an autonomous surface vehicle) to autonomously detect and track an upwelling front. Unlike an autonomous underwater vehicle (AUV)...
Silica scaling in reverse osmosis of groundwater is a significant issue in water stressed areas due to the limitations that scaling imposes on water recovery. While calcium and magnesium scaling potential can be significantly reduced by the use of ion exchange or other softening processes, the silica scaling potential typically remains. Improving the recovery of reverse osmosis by limiting the potential...
The complexity of installations in the oceans to carry out observations on specific processes and for detecting long-term trends have grown significantly in the past years. This applies also to the type and number of sensors that are in use in observing systems. In these days, sensors shall be compatible to different platforms that are in use like floats, gliders or moorings, and accordingly also...
Nowadays, the studies of episodic processes in the ocean is manly done through the innovative facilities called ocean observatories which provide unprecedented amounts of power and two-way bandwidth to access and control sensor networks in the oceans. The most capable ocean observatories are designed around a submarine fiber optic/power cable connecting one or more seafloor science nodes to the terrestrial...
We have designed, built, tested and fielded a decision support system which provides a platform for situational awareness, planning, observation, archiving and data analysis. While still in development, our inter-disciplinary team of computer scientists, engineers, biologists and oceanographers has made extensive use of our system in at-sea experiments since 2010. The novelty of our work lies in the...
With the advent of Autonomous Underwater Vehicles (AUVs) and other mobile platforms, marine robotics have had substantial impact on the oceanographic sciences. These systems have allowed scientists to collect data over temporal and spatial scales that would be logistically impossible or prohibitively expensive using traditional ship-based measurement techniques. Increased dependence of scientists...

Smart Ocean Environments are currently considered a key factor to connect the physical world with the information world. A Smart Ocean Environment can be defined as the combination of a physical environment, a collection of marine instruments gathering heterogeneous data from the environment, an infrastructure for data management and a connectivity solution to convey data from instruments to the Smart...
We describe our implementation of a novel deep ocean sensor network, the MBARI Free Ocean CO2 Enrichment (FOCE). FOCE is a system designed for installation in the deep ocean to enable manipulative experiments that explore the impact of deep ocean increase in CO2 and resulting pH change on ocean biogeochemistry and ecology. This system uses control feedback and pH sensors to inject CO2 into a small...
