The present study investigated the abundance and distribution of protected seagrass associated species within the introduced Halophila stipulacea meadows on St. Eustatius. These species are the queen conch, Caribbean spiny lobster, slender seahorse, green turtle and several species of grouper (Epinephelus …

To limit the pressure on the marine ecosystem, the European Unions’ Marine Strategy Framework Directive (MSFD) was developed to ensure sustainable use of the marine ecosystem. The goal of the MSFD is to achieve Good Environmental Status (GES). To achieve this goal, the MSFD prescribes using Ecosystem-Based …

Marine debris is a growing global problem. Due to the wide ocean dynamics worldwide, predicting the transport of floating marine debris, such as plastic, is difficult. Although large-scale distribution patterns and accumulation zones are recognised and reproduced by numerical models, small-scale prediction …

Plastic pollution has increased over the years and this affects especially seabirds which are vulnerable to this type of pollution. A species that is used as indicator species for plastic pollution is the short-tailed shearwater (Ardenna tenuirostris). These seabirds belong to the procellariids group …

Increased spatial pressures on the marine environment asks for smart use of space in order to safeguard the achievement of environmental, social and economic objectives. Multi-use is seen as a new paradigm for space efficiency and might yield other benefits beyond that. Within the scope of their Policy …

In de afgelopen jaren zijn er meerdere windmolenparken negatief in het nieuws gekomen waar protesten zijn ontstaan tegen de komst van de windmolenparken.

Medicijnresten die vanuit het binnenwater in de Waddenzee stromen, zijn niet zomaar verdwenen. Ze worden nog weken rondgepompt op het ritme van de getijden. Yannick Kalteren, student Kust- en zeemanagement van Hogeschool Van Hall Larenstein onderzocht de uitstroom van zogenaamde opkomende stoffen van …

This thesis project has been carried out at VHL (Van Hall Larenstein University of Applied Sciences) and consists of three different parts; the first part is an experiment in which during 20 days of cultivation the optimum nitrate concentration for protein production in Ulva lactuca is sought. U. lactuca …
