“…Some examples of current autonomous underwater platforms include remote environmental monitoring units (REMUS) (Allen et al, ; Moline, Blackwell, et al, ), SAUV II (Blidberg et al, ; Crimmins et al, ), and the Slocum Glider (Webb, Simonetti, & Jones, ). The REMUS is propeller‐driven and steered using vertical and horizontal fins attached to the back of the body.…”

Dissolved oxygen (DO) concentration is a key indicator of the health and productivity of an aquatic ecosystem. This paper presents a new method for high-resolution characterization of DO as a function of both space and time. The implementation of a new oxygen optode in an Iver2 autonomous underwater vehicle (AUV) is described, which enables the system to measure both absolute oxygen concentration and percentage saturation. Also described are details of AUV missions in Hopavågen Bay, Norway, which consisted of a series of repeated undulating lawnmower patterns that covered the bay. Through offline postprocessing of data, sensor characteristic models were developed, as well as a 3D lattice time series model. The model was constructed by estimating DO at each 3D lattice node location using a 1D Kalman filter that fused local measurements obtained with the AUV. By repeating model construction for several missions that spanned 24 h, estimates of DO as a function of space and time were calculated. Results demonstrated (1) the AUVs ability to repeatedly gather high-spatialresolution data (2) significant spatial and temporal variation in DO in the water body investigated, and (3) that a 3D model of DO provides better estimates of total DO in a volume than extrapolating from only a single 2D plane. Given the importance of oxygen within an ecosystem, this new method of estimating the quantity of DO per volume has the potential to become a reliable test for the health of an underwater ecosystem. Also, it can be refined for detecting and monitoring a range of soluble gases and dispersed particles in aquatic environments, such as dissolved O 2 and CO 2 around production facilities such as fish farms, or dispersed hydrocarbons and other pollutants in fragile ecosystems.

“…Compared with SAUV I, energy system of SAUV II has been optimized and equipped with BP585 solar panel (maximum power of 85 W), Li‐ion battery (2 kW·h), and its endurance has been greatly improved . On the basis of SAUV II prototype, many field experiments have been undertook in Lake George (in June and October, respectively) and Greenwich Bay (in August) in 2004, which focus on the communication and cooperation among multiple AUVs …”

Summary The power supply for ocean robots has always been an important issue since it has a fatal influence on the endurance of these vehicles. However, the marine renewable energy (MRE) has huge potential and can provide the possibility to solve this problem between essential endurance and finite energy in ocean robots. This paper starts with brief introduction of marine energy resource and ocean robots and presents significance of improving ocean robots' endurance, through comparison of their performance characteristics. MRE applied in ocean robots developed or under development, including energy conversion and driving principle, is reviewed, such as solar, wind, tides, waves, thermal energy, etc. Many challenges and difficulties are also discussed in energy exploitation and utilization related to ocean robots. Finally, the prospect for the future development of related technologies is proposed in this paper.

“…semi-fuel cells) are a natural choice for underwater applications, as they are intrinsically pressure compensated and do not need heavy casings-although it is important to avoid interferences between battery effluent and the sensing systems [22 and 23]. Renewable energy systems that utilize various naturally occurring chemicals and conditions in water bodies are options that hold great promise for long-term nutrient sensing, and may include use of (1) methane hydrate fuel cells, (2) microbial fuel cells, (3) sea-surface photovoltaic cells, or (4) motionto-electricity conversion techniques [24][25][26][27][28][29][30][31][32][33][34].…”

New insights into global geochemical cycles can be realized through use of in situ nutrient sensors. Although a number of technological advances have been made, there remain challenges to synoptic, longterm nutrient sensing in marine systems. Resources must be expended to address critical sensor development needs that include reductions in size, cost, power consumption, reagent use, and waste generation, and increases in long-term reliability.
