SPOTS: Spectral properties of submerged and biofouled marine plastic litter

Recent studies have shown that remote sensing of floating marine plastic litter (MPL) is feasible from unmanned aerial systems, aircraft and satellite missions. However, in the infrared (IR) spectrum, water is a strong light absorber which makes the spectral detection and discrimination of plastics challenging. Additionally, MPL is often covered with living organisms and it is unclear what impact different thickness of biofouling may have on the spectral reflectance of floating plastic.

MARLISAT

The objective of the MARLISAT project was to further develop Marine Plastic Monitoring through the use of multiple satellite technologies. In effect, the intention was to use satellite technology to detect Marine litter, track it and forecast it pathways. 4 satellite technologies were combined:

Absolute Navigation at Sub-cm Level - Phase 2

Currently GNSS Systems provide services for instantaneous absolute positioning accuracy of a few meters, assuming no local obstructions above 5-10 degrees elevation, based on the navigation signals broadcast by a MEO constellation.

Detection and tracking of large marine litter based on high-resolution remote sensing time series, machine learning, and ocean current modelling (TRACE)

The overall goal of the TRACE project was to build a remote sensing based fully automated system for the detection and tracking of large marine litter and accumulation patches of smaller litter items in order to obtain precise and reliable data on floating macro-litter regarding their quantity, position, accumulation zones, material properties, floating depth, and sources. The tracking mechanism has been implemented by coupling the daily satellite-based detections with an oceanographic forecasting system and by a two-step object matching approach.

Tackling the plastic debris challenge at its source – Linking EO data with multi-source in-situ data for modelling debris pathways from source to sink

Monitoring areas closer to plastic marine litter sources that can be very well targeted, such as rivers and estuarine systems, has the potential to improve mitigation strategies. Since the area to be monitored is much smaller, mitigation strategies can be spatially focused and even clean-up activities can be more efficient (more targeted). Recent studies showed that floating plastics emitted from the coast depict a much greater chance to rapidly return to land with most litter stranding within a short distance of the river mouth.

POSITION, NAVIGATION AND TIME TRAFFIC LIGHT (PETAL)

The objective of the proposed PNT Traffic Light project is to develop a continuous 24/7 performance monitoring tool for EGNOS/GNSS (and particularly for GPS, GALILEO and EGNOS) on the northern and arctic region of, at least, EGNOS coverage area. In addition to just EGNOS, the tool shall be designed to support assessment of the performance of also other GNSSs (at least GPS and Galileo).

Radiation-hardened single-chip picosecond Time-to-Digital Converter ASIC

Time-to-Digital Converters (TDCs) are crucial elements in many sensor readout systems, such as time-of-flight sensors, laser ranging devices, LiDAR, ultrasonic sensors, particle detectors, etc. To the best of our knowledge, there is currently no rad-hard TDC component available on the market, which could meet the targeted specification defined in this project. The goal of this project is prototyping and lab testing of a radiation-hardened single-chip picosecond TDC in a commercial 65 nm CMOS technology.

Plastic Litter Project: Detection and monitoring of artificial plastic targets with satellite imagery and UAV

There is an urgent need to assess the levels of plastic pollution in the ocean, to allow for future monitoring and determine the efficacy of any remediation put into force. As a consequence, parallel to in situ observations, there is a growing interest in detecting marine debris using remote sensing satellite and UAV imagery. The Marine Remote Sensing Group (MRSG) at the University of the Aegean is one of the few groups worldwide with in-deep experience in developing artificial plastic debris target structures, in different configurations and polymer composition.
