We describe a network of sensors linked by software and the Internet to an autonomous satellite observation response capability. This sensor network is designed with a flexible, modular, architecture to facilitate expansion in sensors, customization of trigger conditions, and customization of responses. This system has been used to implement a global(More)
High quality carbonate chemistry measurements are required in order to fully understand the dynamics of the oceanic carbonate system. Seawater pH data with good spatial and temporal coverage are particularly critical to apprehend ocean acidification phenomena and their consequences. There is a growing need for autonomous in situ instruments that measure pH(More)
Chronic diseases, such as diabetes, exact a considerable social and fiscal burden, both in the United States and worldwide. Diet, exercise and in general the lifestyle can help enormously to manage diabetes. However, especially for children it is not easy to manage diabetes. In this paper we present the design of an Integrated and Personalized Diabetes(More)
The U.S. National Oceanic and Atmospheric Administration (NOAA) Coral Reef Watch (CRW) program has developed a daily global 5-km product suite based on satellite observations to monitor thermal stress on coral reefs. These products fulfill requests from coral reef managers and researchers for higher resolution products by taking advantage of new satellites,(More)
There are a growing number of level 4 (L4; gap-free gridded) sea surface temperature (SST) products generated by blending SST data from various sources which are available for use in a wide variety of operational and scientific applications. In most cases, each product has been developed for a specific user community with specific requirements guiding the(More)
A 690 GHz wide spectral bandwidth heterodyne receiver was developed to observe the J=6→5 rotational emission line of carbon monoxide (CO) in extragalactic sources. This receiver is based on a niobium superconductor-insulator-superconductor (SIS) mixer with a twin-slot antenna in a superconducting NbTiN ground plane. A 4-8 GHz low-noise amplifier was(More)
The National Oceanic and Atmospheric Administration’s Office of Satellite Data Processing and Distribution are generating operational sea surface temperature (SST) retrievals from GOES-9, 10 and 12 satellite imagers. The direct regression based algorithms have been replaced by retrieval schemes based on radiative transfer modeling (RTM). The satellites are(More)
The first recorded eruption of Mount Belinda, on Montagu Island in the South Sandwich Islands, has been ongoing since late 2001 based upon analysis of thermal satellite imagery (1 km pixel size) from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument. Using the automated MODIS Thermal Alert system (Wright et al., 2002) at the University(More)
