OPEN Call for Transnational Access to European Aquatic Mesocosm Facilities in 2020

The EU Research Infrastructure project AQUACOSM has opened the 3rd CALL for Transnational Access to fund participation or leadership of mesocosm experiments in 2020. We open for access to more than 33 aquatic mesocosm facilities, located at 15 AQUACOSM partners throughout Europe. In total AQUACOSM offers more than 11500 person-days of TA between Jan 2018 and Oct 2020. This CALL opens for >3800 person days of Transnational Access in 2020. AQUACOSM offers funding for mesocosm experiments throug… Read more »

Joining AQUACOSM TA 2018 mesocosm experiments at the CNRS-MARBEC MEDIMEER while pregnant and later with a newborn baby

Katharina Bading, PhD student, Department of Biology, Norwegian University of Science and Technology (NTNU), Trondheim, Norway Back in fall 2017, I was excited that our MIWA user group application for the AQUACOSM Transnational Access program was granted so that our NTNU team was able to join the WARMPLANK mesocosm project (lead by Behzad Mostajir) on “Effects of warming on the Mediterranean plankton food web functioning” at the CNRS-MARBEC MEDIMEER mesocosm facility in Sète, Southern France. Tw… Read more »

The Summer in Spring project “Heat wave effects on Mediterranean Plankton communities: Resistance, Resilience and Recovery” attracted 18 researchers for a total of 442 person/days in the frame of AQUACOSM Transnational Access realized in the CNRS-MARBEC MEDIMEER mesocosm facility during May-June 2019

Currently, summer time reaches earlier in the most part of Europe and this could affect all the aquatic organisms. To study the resistance, resilience and recovery of plankton communities to heatwaves occurring in late spring/early summer the “Summer in Spring” mesocosm experiment was proposed and led by F. Vidussi and B. Mostajir at CNRS-MARBEC MEDIMEER mesocosm facility in Sète, in the southern France in May-June 2019. During 10 days, as a heat wave simulation, several pelagic in situ mesocosm… Read more »

Nitrogen Cycling in Climate-impacted Lake Mesocosms (NCyCLMe)

Mark J. McCarthy, Shannon M. Collin, Erik Jeppesen, and Silvia E. Newell Wright State University, Department of Earth and Environmental Sciences Dayton, OH USA Cyanobacterial harmful algal blooms (cyanoHABs, also known as blue-green algae blooms) are a global problem, fouling water with surface scums and toxins. CyanoHABs are caused by excess nutrient loading (phosphorus and nitrogen) from fertilizer and/or wastewater. Historically, research and management efforts have focused on reducing phosph… Read more »

SYKE Marine Research Centre opens Indoor Mesocosm Facility for international access during 2019

SYKE Marine Research Centre will open our brand new Indoor Mesocosm Facility for international access during 2019 through the Transnational Access procedure of the H2020 project AQUACOSM. Please feel free to spread the news to potentially interested researchers within your networks. We welcome you to do a research visit to our premises in Helsinki, Finland! All expenses regarding travel, daily allowance covering board & lodging in Helsinki, plus minor expenses in doing experimental work will… Read more »

Weathering of polymeric particles in semi terrestrial environments – a mesocosm study with PVC

Unique and highly diverse properties of plastics, their easily processing and the low production costs have lead steadily increasing plastic production reaching 322 million tons worldwide in 2015. Plastics have delivered many benefits to society in various sectors; however global plastics pollution is a consequence of unsustainable use, uncontrolled and inadequate plastic disposal and waste management. Enhanced performance and persistency of plastic products is achieved by additives, such as pla… Read more »

TA access at the Artificial Pond and stream system of the Umweltbundesamt in 2018

Project title: Metformin Transformation in a Large Scale Artificial River System Project acronym: TransMet Project duration: May to August 2018 Metformin is one of the most commonly prescribed antidiabetic pharmaceuticals on the global scale and recent studies indicate that metformin might cause endocrine disrupting effects in fish. It enters the waste water untransformed as it is no metabolised in humans. In addition, wastewater treatment plants are not designed to remove pharmaceuticals like m… Read more »

Phytoplankton in the mesocosms

Are some species of phytoplankton favoured by turbulent water? For two weeks, an international research team has utilized the mesocosm facility at Umeå Marine Sciences Center (UMF) to study how the movement of the water affects different species of phytoplankton. In Bath, England, the local authorities have problems with large algae blooms in drinking water reservoirs. Tests based on different stirring techniques has been adopted in order to solve the problem. The University of Bath has also ini… Read more »

Impact of Microplastics on food web structure and functions of shallow freshwater lakes at METU Mesocosm System, Limnology Laboratory, Middle East Technical University, Ankara, Turkey

Approximately 311 million metric ton of plastics were produced in 2014 alone, and production is steadily increasing each year. Up to 10 % of the plastic produced each year worldwide ends up in the aquatic environment, where it persists and accumulates. The sources of microplastics include fragmentation of larger items entering by rivers, runoff, tides, winds, and catastrophic events, together with at-sea sources. There are also direct inputs of microplastics as micrometer-sized particles, such a… Read more »
