The Jason II virtual control van system, data acquisition system, web-based event logger, and SeaNet
Scientific underwater remotely operated vehicles (ROVs) collect data from multiple video cameras and scientific instruments. This
integrated information is often only available in an ROV control-van during operations. Although all the data is logged, it is
difficult for scientists to re-create a combined display of this data and have the ability to review and access an entire cruise dataset
easily. We introduce a methodology of taking continuous real-time information snapshots (infosnaps) during interesting events and
at regular time intervals for complete data coverage. These infosnaps capture four simultaneous video sources, vehicle data,
instrument data, and event data as entered by scientists. The infosnaps are automatically cataloged and immediately accessible and
searchable via a web-browser. We developed, built, and deployed the Jason II Virtual Control Van system on seven Jason cruises.
The system has captured over 50,000 control-van infosnaps, containing more than 200,000 images co-registered with vehicle
telemetry and scientific instrument data. The Virtual Control Van is designed for both scientific collaboration and
public/educational outreach. It has been integrated with the SeaNet system to provide remote on-shore access. The report describes
the Jason II Virtual Control Van system and includes instructions for setting up the system in the field.Funding was provided by the W. M. Keck Foundation under Grant No. 991735
4DGeoBrowser : a web-based data browser and server for accessing and analyzing multi-disciplinary data
This report describes the 4DGeoBrowser software system. The GeoBrowser is a web-based application developed at the Woods
Hole Oceanographic Institution by Steven Lerner and Andrew Maffei. It has been designed with the goal of creating, accessing, and
analyzing repositories of oceanographic datasets that have been generated by investigators in differing scientific disciplines. Once
the information is loaded onto a Geobrowser server the investigator-user is able to login to the website and use a set of data access
and analysis tools to search, plot, and display this information. GeoBrowser servers are also capable of processing commands that
are submitted remotely via HTTP URLs or email. Scientists are able to use this capability to make calls to the GeoBrowser server
and generate click-able maps, tables of urls, and customized HTML pages. These can then be used to enhance websites associated
with scientific projects. Examples of supporting scientific website functionality that includes time series plotting, data delivery by
email, geo-spatial plotting of interdisciplinary data, map-based search capabilities and other functionality are presented in this
report. The report includes examples of GeoBrowser application websites, a user manual, and a reference guide. In addition, the
concept of Electronic Index Cards (EICs) is presented
Complementary Patents and Market Structure
Many high technology goods are based on standards that require several essential patents owned by different IP holders. This gives rise to a complements and a double mark-up problem. We compare the welfare effects of two different business strategies dealing with these problems. Vertical integration of an IP holder and a downstream producer solves the double mark-up problem between these firms. Nevertheless, it may raise royalty rates and reduce output as compared to non-integration. Horizontal integration of IP holders solves the complements problem but not the double mark-up problem. Vertical integration discourages entry and reduces innovation incentives, while horizontal integration always benefits from entry and innovatio
At Sea Test 2 deployment cruise : cruise 475 on board R/V Oceanus September 22 – 26, 2011 Woods Hole –Woods Hole, MA
The R/V Oceanus, on Cruise 475, carried out the deployment of three moorings for the
Coastal and Global Scale Nodes (CGSN) Implementing Organization of the NSF Ocean
Observatories Initiative. These three moorings are prototypes of the moorings to be used
by CGSN at the Pioneer, Endurance, and Global Arrays. Oceanus departed from Woods
Hole, Massachusetts on September 22, 2011 and steamed south to the location of the
mooring deployments on the shelf break. Over three days, September 23-25, Oceanus
surveyed the bottom at the planned mooring sites, deployed the moorings, and carried out
on site verification of the functioning of the moorings and moored hardware. Oceanus
returned to Woods Hole on September 26, 2011.Funding was provided by the National Science Foundation

Acoustic and oceanographic observations and configuration information for the WHOI moorings from the SW06 experiment
This document describes data, sensors, and other useful information pertaining to the moorings that were
deployed from the R/V Knorr from July 24th to August 4th, 2006 in support of the SW06 experiment. The
SW06 experiment was a large, multi-disciplinary effort performed 100 miles east of the New Jersey coast. A
total of 62 acoustic and oceanographic moorings were deployed and recovered. The moorings were deployed in
a “T” geometry to create an along-shelf path along the 80 meter isobath and an across-shelf path starting at 600
meters depth and going shoreward to a depth of 60 meters. A cluster of moorings was placed at the
intersection of the two paths to create a dense sensor-populated area to measure a 3-dimensional physical
oceanography. Environmental moorings were deployed along both along-shelf and across-shelf paths to
measure the physical oceanography along those paths. Moorings with acoustic sources were placed at the outer
ends of the “T” to propagate various signals along these paths. Five single hydrophone receivers were
positioned on the across shelf path and a vertical and horizontal hydrophone array was positioned at the
intersection of the “T” to get receptions from all the acoustics assets that were used during SW06.Funding was provided by the Office of Naval Research under Contract

HERALD (Health Economics using Routine Anonymised Linked Data)
<b>Background</b>
Health economic analysis traditionally relies on patient derived questionnaire data, routine datasets, and outcomes data from experimental randomised control trials and other clinical studies, which are generally used as stand-alone datasets. Herein, we outline the potential implications of linking these datasets to give one single joined up data-resource for health economic analysis.<p></p>
<b>Method</b>
The linkage of individual level data from questionnaires with routinely-captured health care data allows the entire patient journey to be mapped both retrospectively and prospectively. We illustrate this with examples from an Ankylosing Spondylitis (AS) cohort by linking patient reported study dataset with the routinely collected general practitioner (GP) data, inpatient (IP) and outpatient (OP) datasets, and Accident and Emergency department data in Wales. The linked data system allows: (1) retrospective and prospective tracking of patient pathways through multiple healthcare facilities; (2) validation and clarification of patient-reported recall data, complementing the questionnaire/routine data information; (3) obtaining objective measure of the costs of chronic conditions for a longer time horizon, and during the pre-diagnosis period; (4) assessment of health service usage, referral histories, prescribed drugs and co-morbidities; and (5) profiling and stratification of patients relating to disease manifestation, lifestyles, co-morbidities, and associated costs.<p></p>
<b>Results</b>
Using the GP data system we tracked about 183 AS patients retrospectively and prospectively from the date of questionnaire completion to gather the following information: (a) number of GP events; (b) presence of a GP 'drug' read codes; and (c) the presence of a GP 'diagnostic' read codes. We tracked 236 and 296 AS patients through the OP and IP data systems respectively to count the number of OP visits; and IP admissions and duration. The results are presented under several patient stratification schemes based on disease severity, functions, age, sex, and the onset of disease symptoms.<p></p>
<b>Conclusion</b>
The linked data system offers unique opportunities for enhanced longitudinal health economic analysis not possible through the use of traditional isolated datasets. Additionally, this data linkage provides important information to improve diagnostic and referral pathways, and thus helps maximise clinical efficiency and efficiency in the use of resources
