Abstract Throughout the past decade, many studies have reported adverse effects in biota following microplastic exposure. Yet, field is still emerging as current understanding of toxicity limited. At same time, recent legislative mandates required environmental regulators to devise strategies mitigate pollution and develop health-based thresholds for protection human ecosystem health. The publication rate also presents a unique challenge scientists, managers, other communities may find it...
The analysis of microplastics (MP) is time-consuming which limits our capacity to monitor and mitigate plastic pollution. Here, near infrared (1000-2500 nm) hyperspectral imaging (NIR-HSI) offers an advantage over other spectroscopic techniques because it can rapidly image large areas relative systems. While NIR-HSI successfully detect MP, accuracy limitations the method have not been fully explored. In addition, lack open databases pipelines increases barrier use. this work, we developed a...
Data on MP in aquatic environments have low resolution space and time. Scaling up sampling increasing analysis throughput are the main bottlenecks. We combined two approaches: an uncrewed surface vehicle (USV) near infrared hyperspectral imaging (NIR-HSI) for of > 300 μm. collected 35 water samples over 4 d a coastal area. Samples were analyzed using NIR-HSI Fourier transform spectroscopy (FTIR). Spiked used to determine recovery. conclude that USV can mitigate issues traditional trawls like...
In-situ ocean observations are essential for satellite data validation, improving the reliability of environmental monitoring, providing modeling, and informing decision-making processes that impact policy management. We present a small, versatile user-friendly uncrewed surface vehicle (USV) equipped with diverse sensor payloads real-time, in-situ sensing. Our approach focuses on making technological solutions available to non-expert users, in real time efficient productive field campaigns....
Abstract This paper aims to guide the stakeholder engagement process related plastic pollution research in marine environments. We draw on advice identified during an online workshop (Ocean Plastic Workshop 2022) organized by Early Career Ocean Professionals (ECOPs) from 11 countries, held April 2022. International experts and participants discussed their experiences collaborative development implementation of ocean projects worldwide, guided three main questions: (i) What is role scientists...
In this paper, we present a Portable Catamaran Drone (PCD) - an Uncrewed Surface Vehicle (USV) that may significantly improve the scalability of surface water particle sampling using plankton net. We preset vehicle design and evaluate its potential during field-trials.
The analysis of microplastics (MP) is time-consuming which limits our capacity to monitor and respond plastic pollution. Here, infrared hyperspectral imaging (IR-HSI) offers an advantage over other spectroscopic techniques because it can rapidly image large areas relative systems. Detection MP using IR-HSI has been demonstrated for multiple polymer types, however accuracy limitations the method have not fully explored. In addition, lack open databases pipelines increases barrier use. this...
