Book Description
In situ autonomous chemical sensors, combined with the right deployment platforms provide novel, powerful tools for oceanographers to observe biogeochemical processes on unprecedented spatial and temporal scales. However, many aspects of chemical sensor technology have not yet reached full maturity, preventing routine use by the community at large. This dissertation aims to fill this critical need in ocean observing technology, with a focus on Ion Sensitive Field Effect Transistor (ISFET) pH sensors for profiling float applications. Following a brief introduction to the current status of marine chemical sensor technology, the four chapters address the various steps involved in sensor development: sensor characterization, calibration, data quality control (QC), and a modeling effort using sensor data. Chapter 2 introduces a simple QC protocol for profiling float oxygen data by comparison to a monthly climatology. This protocol can constrain O2 at the surface to better than 3%, and detect sensor drift with high confidence. Similar approaches can be taken to QC other chemical sensors data from profiling floats. Chapter 3 characterizes the response of the ISFET pH sensor and the Chloride-Ion Selective Electrode by comparison to the hydrogen electrode and the silver-silver chloride electrode, respectively. Both electrodes showed near-Nernstian response, thus the error in pH due to non-theoretical behavior of the electrodes is negligible over the oceanic range of pH and salinity. Chapter 4 quantifies the effect of pressure on the pH of certified tris buffer prepared in synthetic seawater. Assignment of pH values to certified buffer solutions is essential for sensor calibration. As the number of pH sensors deployed under high pressures is expected to increase, this chapter will fill a critical need in sensor validation and traceability. Chapter 5 presents habitat-specific ocean acidification projections between 2012 and 2100 for 4 habitats in the upper 100 m of the Southern California Bight. The projections were generated by combining high frequency pH sensor data, a regional empirical relationship of the CO2 system, and hydrographic data to characterize the properties of upwelled waters. Habitat specific acidification signals were predicted, and implications for future ocean acidification research are discussed.

Book Description
Challenges and Innovations in Ocean In-Situ Sensors: Measuring Inner Ocean Processes and Health in the Digital Age highlights collaborations of industry and academia in identifying the key challenges and solutions related to ocean observations. A new generation of sensors is presented that addresses the need for higher reliability (e.g. against biofouling), better integration on platforms in terms of size and communication, and data flow across domains (in-situ, space, etc.). Several developments are showcased using a broad diversity of measuring techniques and technologies. Chapters address different sensors and approaches for measurements, including applications, quality monitoring and initiatives that will guide the need for monitoring. Integrates information across key marine and maritime sectors and supports regional policy requirements on monitoring programs Offers tactics for enabling early detection and more effective monitoring of the marine environment and implementation of appropriate management actions Presents new technologies driving the next generation of sensors, allowing readers to understand new capabilities for monitoring and opportunities for another generation of sensors Includes a global vision for ocean monitoring that fosters a new perspective on the direction of ocean measurements

Book Description
This book both describes the chemical parameters that must be measured in the ocean in order to improve our understanding of the ocean's role in the global carbon cycle and recommends technologies of analytical chemistry that could be applied to these parameters. Additionally, the volume recommends how the federal government, ocean scientists, and analytical chemists could work together more closely to speed development of new instruments and implementation of new techniques.

Book Description
Over the past ten years, a number of new large-scale oceanographic programs have been initiated. These include the Climate Variability Program (CLIVAR) and the recent initiation of the Geochemical Trace Metal Program (GEOTRACES). These studies and future projects will produce a wealth of information on the biogeochemistry of the world's oceans. Aut

Book Description
The United States has jurisdiction over 3.4 million square miles of ocean in its exclusive economic zone, a size exceeding the combined land area of the 50 states. This expansive marine area represents a prime national domain for activities such as maritime transportation, national security, energy and mineral extraction, fisheries and aquaculture, and tourism and recreation. However, it also carries with it the threat of damaging and outbreaks of waterborne pathogens. The 2010 Gulf of Mexico Deepwater Horizon oil spill and the 2011 Japanese earthquake and tsunami are vivid reminders that ocean activities and processes have direct human implications both nationally and worldwide, understanding of the ocean system is still incomplete, and ocean research infrastructure is needed to support both fundamental research and societal priorities. Given current struggles to maintain, operate, and upgrade major infrastructure elements while maintaining a robust research portfolio, a strategic plan is needed for future investments to ensure that new facilities provide the greatest value, least redundancy, and highest efficiency in terms of operation and flexibility to incorporate new technological advances. Critical Infrastructure for Ocean Research and Societal Needs in 2030 identifies major research questions anticipated to be at the forefront of ocean science in 2030 based on national and international assessments, input from the worldwide scientific community, and ongoing research planning activities. This report defines categories of infrastructure that should be included in planning for the nation's ocean research infrastructure of 2030 and that will be required to answer the major research questions of the future. Critical Infrastructure for Ocean Research and Societal Needs in 2030 provides advice on the criteria and processes that could be used to set priorities for the development of new ocean infrastructure or replacement of existing facilities. In addition, this report recommends ways in which the federal agencies can maximize the value of investments in ocean infrastructure.
