[RAW VALIDATED DATA] Navigation and meteorological data during the Tara Oceans expedition 2009-2013
The Tara Oceans Expedition (2009-2013) was a global survey of ocean ecosystems aboard the Sailing Vessel Tara. It carried out extensive measurements of environmental conditions and collected plankton (viruses, bacteria, protists and metazoans) for later analysis using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data publication provides permanent links to original and updated versions of validated data files containing navigation and meteorological data collected during the entire Tara Oceans Expedition (2009-2013)

Navigation and meteorological data during Tara Oceans expedition 2009-2013
The Tara Oceans Expedition (2009-2013) sampled the world oceans on board a 36 m long schooner, collecting environmental data and organisms from viruses to planktonic metazoans for later analyses using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. During the entire expedition (2009-2013), underway measurements were obtained from a meteorological station (BATOS), a thermosalinograph (TSG, SBE 45), a Fast Repetition Rate Flurometer (FRRF, LIFT-FRR01), and a spectrophotometer (WETLabs AC-S). In 2013 underway measurements were enhanced by adding a Photosynthetically Available Radiation (PAR) sensor (QCP2350, Biospherical Instruments, Inc.), a laser spectrofluorometer (WETLabs ALFA, Chekalyuk et al., 2012) that replaced the FRRF, a spectral backscattering sensor (WETLabs Eco-bb3), a pCO2 sensor (ProOceanus CO2-Pro), a pH sensor (Satlantic, SeaFET) and a particle imaging system triggered by chlorophyll-a fluorescence (a prototype of McLane Research Laboratories' Imaging FlowCytobot, Sosik Lab, WHOI). Discrete measurements of CDOM absorption measurements were made using an Ultrapath (WPI Inc.) to calibrate the in-line AC-S. Hence the AC-S was also used to provide CDOM absorption in addition to particulate matter properties.
The present dataset contains navigation and meteorological data measured during the 2009-2013 campaigns of the Tara Oceans Expedition. Latitude and Longitude were obtained from TSG data. The time stamp of this data set is harmonised with that of other underway data in this collection
Designing for TARA: The radar control unit
This thesis describes the work done on a control system for the Transportable Atmospheric RAdar (TARA), which is located at the Cabauw Experimental Site for Atmosperic Research (CESAR). It describes the way in which this radar control unit was implemented within the TARA, by making use of a high-level programming language. The control unit consists of a PXI-system of National Instruments, LabVIEW software, a DDS from Analog Devices and provided Matlab code. The project resulted in a working prototype. The TARA itself is a FM-CW radar with the possibility of sending and receiving in multiple polarizations and orientations for weather measurements. The system was tested and most functions worked properly. During the test, the measurements with the new system generated the same data as the current system. This proved that the system is working correctly, which is of great importance for the ATMOS group, because they are planning to transport the TARA to a measurement campaign in France in 2012 using the upgraded system.Remote Sensing of the EnvironmentElectrical Engineering, Mathematics and Computer Scienc
Engagement, Learning, Outreach, and Fun in 60 Seconds: Button Making at the Rutgers University Libraries
Button making is a low-cost, high-impact, pop-up makerspace activity that libraries can use to facilitate outreach, connect patrons with collections, teach about copyright, and promote creativity and fun, all in just 60 seconds.
In the fall of 2016, the Rutgers University Libraries- New Brunswick Learning and Engagement team spent $518 to purchase a button maker and supplies to make 1,000 buttons. Since then, the libraries have collaborated on button projects with many departments on campus including the Rutgers Art History Student Association, the Zimmerli Art Museum, and the School of Arts & Sciences Honors program. These partnerships have helped the libraries build strong ties with the Rutgers New Brunswick communities and attracted a devoted group of button makers who regularly come to library events.
Making a button provides quick moment of engagement between a patron and a library staff member, but it is from these kinds of meaningful brief encounters that libraries can learn about their patrons’ lives and needs. These encounters can also be a source for the powerful stories, images, and statistics that help libraries demonstrate their impact and value to their communities.thanks for your help, please let me know any questions. I think we can put this version in SOAR? Best, MC
Harmonised data from underway navigation, meteorology and surface water measurements during the Tara Oceans expedition in 2009-2013

[RAW VALIDATED DATA] Properties of seawater and particulate matter from a WETLabs ALFA hyperspectral laser spectrofluorometer mounted on the continuous surface water sampling system during the Tara Oceans expedition 2009-2013
The Tara Oceans Expedition (2009-2013) sampled the world oceans on board a 36 m long schooner, collecting environmental data and organisms from viruses to planktonic metazoans for later analyses using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set provides raw validated data of continuous measurements made with an Aquatic Laser Fluorescence Analyzer (ALFA) (Chekalyuk et al., 2014), connected in-line to the TARA flow through system during 2013. The ALFA instrument provides dual-wavelength excitation (405 and 514 nm) of laser-stimulated emission (LSE) for spectral and temporal analysis. It offers in vivo fluorescence assessments of phytoplankton pigments, biomass, photosynthetic yield (Fv/Fm), phycobiliprotein (PBP)-containing phytoplankton groups, and chromophoric dissolved organic matter (CDOM) (Chekalyuk and Hafez, 2008; 2013A). Spectral deconvolution (SDC) is used to assess the overlapped spectral bands of aquatic fluorescence constituents and water Raman scattering (R). The Fv/Fm measurements are spectrally corrected for non-chlorophyll fluorescence background produced by CDOM and other constituents (Chekalyuk and Hafez, 2008). The sensor was cleaned weakly following the manufacturer recommended protocol
The new real-time measurement capabilities of the profiling TARA radar
In the past 10 years, the S-band FM-CW TARA (Transportable Atmospheric RAdar), placed at the Cabauw Experimental Site for Atmospheric Research (CESAR), provided in real-time vertical profiles of the Doppler moments. Classical spectral processing was carried out. The polarimetric and multi-beam measurement capabilities of the radar were not exploited in real-time. It was only possible to acquire raw data for case studies. Based on them, new algorithms were developed using spectral polarimetry and the multi-beam capability of TARA. They have been tested during the COPS (2007) and EUCAARI-IMPACT campaigns (2008). To measure in real-time the Doppler moments of three beams, the differential reflectivity, the linear depolarization ratio, the horizontal wind and the vertical mean Doppler velocity, it became necessary to upgrade TARA. This resulted in a new design of the radar control unit and a new processing based on spectral polarimetry. This major upgrade took place in 2011. TARA can now deliver multi-parameters profiles with high spatial and time resolution and raw data in real-time. They are stored with the NetCDF format. Furthermore, detailed quick-looks of all the observables are available in real-time at http://ftp.tudelft.nl/TUDelft/irctr-rse/tara/index.html. For the design of the radar control unit and processing, a flexible solution that can process the data in a high level programming language, was chosen. This was done to be able to easily implement future developments in radar signal processing and algorithms.Geoscience & Remote SensingCivil Engineering and Geoscience

[RAW VALIDATED DATA] Properties of seawater (pH total scale) from a Satlantic SeaFET instrument mounted on the continuous surface water sampling system during the Tara Oceans expedition 2009-2013
The Tara Oceans Expedition (2009-2013) sampled the world oceans on board a 36 m long schooner, collecting environmental data and organisms from viruses to planktonic metazoans for later analyses using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set provides raw validated data of continuous pH measurements made during 2013 expedition with a Satlantic SeaFET instrument that was connected to the flowthrough system. Data calibration was performed according to Bresnahan et al. (2014) (using spectrophotometric pH measurements on discrete samples (Clayton and Byrne 1993). pH_internal values were taken to calibrate the data (rather than pH_external) because of the better calibration coefficient (there was no trend associated with it). The equations of Clayton and Byrne (1993) was used to compute pH from the measured absorbance values at the temperature of measurement. The data was converted to in situ temperature using the “CO2-sys” program (van Heusen et al. 2011)
