Waterside Security 2010 (WSS2010) Conference: Post Conference Report. Kessel, R.; Zakharia, M. NURC-MR-2011-002. February 2011

The 2nd International Conference on Waterside Security was hosted by NURC, Carrara, Italy, 3-5 November 2010. This report provides summary statistics of the conference, a summary of the workshops, remarks form the WSS2010 Chairman (Ronald Kessel), and acknowledges key contributors.

Algorithmic analysis of the NURC SAS processing chain. Schmaljohann, H.; Groen, J. NURC-MR-2011-003. August 2011

In this document the main parts of the SAS processing program based on the MATLAB code at NURC are displayed in a flow chart, and the different processing steps are summarized. The text should provide some help for those who want to work with the NURC SAS processing chain. Be aware that the less relevant details (i.e., those which are only included for a faster processing) are not listed in this text.

Combined analysis of LOGMEC16 oceanographic glider and satellite data and their correlation Combined analysis of LOGMEC16 oceanographic glider and satellite data and their correlation

Combined analysis of LOGMEC16 oceanographic glider and satellite data and their correlations. Borrione, Ines; Oddo, Paolo; Russo, Aniello; Coelho, Emanuel. CMRE-MR-2017-003. April 2017.

During the LOGMEC16 (Long-Term Glider Mission for Environmental Characterisation) sea trial carried out in the eastern Ligurian Sea (North-western Mediterranean Sea), two oceanographic gliders rated to a maximum depth of 1000m were operating continuously from 3 May to 27 June 2016. When possible, glider tracks were synchronised with the footprints of contemporaneous altimeters (i.e., Jason 2, SARAL/AltiKa and CryoSat-2). Temperature and salinity measured by the gliders that were co-localised with the altimeter passages, were used to calculate along-track dynamic heights. The latter were then compared with the near-real time absolute sea level CMEMS-TAPAS (Copernicus Marine Environment Monitoring Service - Tailored Altimetry Products for Assimilation Systems) product. Where available, the CMEMS near-real time 1 km resolution, Aqua-MODIS ocean colour data was also used as a tracer of the main oceanographic features of the region. Comparison between SLA derived from gliders and TAPAS along common transects, shows that patterns, variability, and scales in the filtered SLA are comparable to those obtained from glider measurements. Differences are mostly explained by the fact that gliders have sampled at different times the same structures, which were moving northwards at ~ 0.16 m s-1. Conversely, the unfiltered SLA shows a variability that is not fully captured by the in situ measurements. Both gliders and SLA provide evidence of mesoscale variability (i.e., meanders) likely due to the baroclinic instability of the Northern Current. The scales of these structures (i.e., amplitude of 39 km, and propagation speed of 0.16 m s-1) are in agreement with those previously described in literature, and are confirmed by the larger scale ocean colour measurements.

Manual of BORIS-SSA: Bottom Response from Inhomogeneities and Surface using the Small-Slope Approximation, Version 1.01. M-152. July 2005.

The description of a software tool capable of simulating, in the time domain, the acoustic time series resulting from scattering from various seafloor types and acoustic source/receiver geometries is presented in the form of a user manual. This package, named BORIS-SSA, is an upgrade, with various new features, of BORIS-3D. The parameters of the model characterize the sonar directivity and pulse shape, the geometrical configuration of the scattering problem and the geo-physical characteristics of the seafloor (but also sea surface or other surface). This surface can be generated to have various statistical behaviours or can be obtained from deterministic data based on the surface heights (profilometry, stereo-photogrammetry, bathymetry, etc). The package is platform independent and user friendly. This report is intended as a detailed description of the implementation on a source code level. A short introduction to the model underlying the package and a comprehensive demonstration program are also given.

NURC OpenSea hybrid tactical gaming platform for maritime technology concepts of use: roles and requirements in 2012. Kessel, R.; Leonard, M.; Strode, C. NURC-MR-2012-001. March 2012

OpenSea is a modelling and simulation platform for hybrid tactical gaming. It is a tool for the preliminary exercise of new technology concepts by immersion into virtual operation for early de-risking of new technologies. OpenSea features now in the NURC programmne of work as a tool for use by other projects rather than as a project in its own right. The purpose of this report is to review the origin of OpenSea and its roles, applications, configuration, linkages in NATO programmes, and ongoing requirements extending into the first half of 2012. The report therefore provides programmatic context for OpenSea into 2012.
