FP7-OCEAN-2013 — SCHeMA: Integrated in situ chemical mapping probes

Abstract

Coastal areas are vulnerable ecosystems comprising unique biological niches that require protection. Identification of relevant types of hazards at the appropriate temporal and spatial scale is crucial to detect their sources and origin, to understand the processes governing their magnitude and distribution, and to ultimately evaluate and manage their risks and consequences preventing economic losses. SCHeMA aims to provide an open and modular sensing solution for autonomous in situ high resolution mapping of a range of anthropogenic and natural chemical compounds coupled to master bio-physicochemical parameters. User-friendly data discovery, access and download as well as interoperability with other projects will be achieved via dedicated interface compatible with INSPIRE and GEO/GEOSS standards and principles.

Compact and Low-Cost Fluorescence Based Flow-Through Analyzer for Early-Stage Classification of Potentially Toxic Algae and in Situ Semiquantification

“…For this purpose, the ALPACA, which was calibrated in advance, was incorporated into a pressure-stable submersible housing. 30 A solution (70% ethanol) was included in the submersible probe, enabling a blank measurement before each measurement circle. The submersible probe was installed at a depth of 4.6 m under the surface throughout the entire period, including small spatial variabilities due to tides.…”

“…The long-term stability of the ALPACA and its analytical performance were evaluated during a field campaign at the Port of Genoa (CNR station: 44°23′45.6″ N, 8°55′51.6″ E; Figure S13) between February 14–March 13, 2017. For this purpose, the ALPACA, which was calibrated in advance, was incorporated into a pressure-stable submersible housing . A solution (70% ethanol) was included in the submersible probe, enabling a blank measurement before each measurement circle.…”

“…The design of the ALPACA has been developed in the frame of the FP7-SCHeMA project (2015). 30 ALPACA is constructed as a miniaturized multiwavelength fluorometer operating in a modular way to enable easy adjustment for different requirements and applications. The main part consists of an optics block machined from a polyoxymethylene copolymer with a geometrical dimension of 28 mm × 35 mm × 16 mm.…”

Spectral Characterization of Eight Marine Phytoplankton Phyla and Assessing a Pigment-Based Taxonomic Discriminant Analysis for the in Situ Classification of Phytoplankton Blooms

“…Discontinuous fluorescence spectra were acquired for each algal sample with the miniaturized, low-cost ALPACA, which has been developed in the frame of the FP7-SCHeMA project (2015) and which was presented earlier. , The setup of the ALPACA, an acronym for Advanced Luminescence-Based Phytoplankton Analysis and Classification Appliance, is shown in Figure D. The detection unit of the ALPACA features eight excitation channels, four at each side, and four emission channels aligned at right angles.…”
