TECHNICAL ABSTRACT: This paper proposes development of a low-cost water monitoring system wirelesslynetworked to upload data to FieldKit for cloud based data visualization and validation. This will enable citizen scientists to collect a variety of parameters including conductivity, temperature, depth, and ocean noise measurements on an adhoc basis while contributing to a large data repository whic ...

TECHNICAL ABSTRACT: A flow micro-photometer is proposed that can measure absorption and backscatter from single aquatic particles including phytoplankton, detritus and minerals. This instrument will make use of a novel adaptive diaphragm to define an analysis region of interest that exactly matches the size, shape and orientation of each particle being analyzed. A micro-fluidic chip will be used t ...

TECHNICAL ABSTRACT: Tropospheric oxidation capacity is dominated by HOx photochemistry, however halogen atoms and oxides significantly affect these chemical cycles. A sensitive and robust measurement of gaseous HCl is critically important to improve our understanding of halogen chemistry and its impacts on the spatial and temporal oxidation capacity of the atmosphere. In Phase I, we met all of our ...

During the Phase I program, Aurora conducted a comprehensive survey of potential platforms that included government owned and furnished UAVs and manned aircraft as well as Aurora’s Centaur Optionally Piloted Aircraft (OPA). The survey concluded, in part, that UAVs offer a significant improvement in data collection capability when compared to manned aircraft that are currently fielded by NOAA. ...

A preliminary design of a mobile receiver system for intra-cloud lightning detection, mapping, and tracking was completed and analyzed during the Phase I program. The direction-finding (DF) receiver design is small enough for use on small UAVs and utilizes the full VHF spectrum. The lightning Mapping Unmanned Sensor (LITMUS) design will be finalized, fabricated, assembled, and demonstrated durin ...

We propose to develop a system that can automatically detect, track, measure, and classify fish seen in video collected by stationary underwater cameras. Our approach makes use of a novel method for detecting motion that can mitigate false alarms due to swaying underwater vegetation. We propose a novel technique for tracking the fish in three spatial dimensions allowing for improved knowledge of ...

Greenhouse gas (GHG) emissions to the atmosphere are primary drivers of global climate change and hence there is a crucial need to quantify their sources and sinks. A general technique to constrain source and sink strengths is the analysis of the relative proportions of isotopic variants of GHG's. These measurements must be performed with extremely high precision. The gold standard technique, i ...

There are currently no inexpensive observing systems that detect temperature, salinity and currents under the ocean's surface - all important factors in predicting the intensity of hurricanes. Boston Engineering proposes to develop the Multi-Purpose Above Surface/Below Surface Expendable Dropsondes (MASED). Our design builds on the highly successful air dropsondes already in use, combined with a ...

Toyon proposes development of a system which performs automated analysis of images for fish population monitoring and fishing regulation enforcement applications. The proposed system is capable of processing images collected from aircraft, including unmanned aerial vehicles, as well as images collected using boat-mounted or handheld cameras used to observe fish catches landed on the decks of vess ...

Spontaneous Parametric Down Conversion (SPDC) is currently an active research area in quantum communications (QC) to develop entangled single photon sources. However, the bandwidth of current SPDC sources is too broad for many applications. NIST researchers have modeled a solution to this problem that reduces the bandwidth by >50. We propose to fabricate a prototype of the NIST device by developin ...
