Mesocosm Facility at Umeå Marine Sciences Center (MF-UMSC)

AQUACOSM-plus

1) Open time slot: The Mesocosm Facility at Umeå Marine Sciences Center (MF-UMSC) will open for Transnational Access for an open time slot from September to October 2021.

Deadline for TA application at MF-UMSC is 30 April 2021, 13:00 CET.

2) First full winter mesocosm experiment in arctic like conditions at Umeå Marine Sciences centre

Timing: November 2021 to May 2022

Project Lead: Henrik Larsson

Project Description: Climate change is not evenly distributed around the world and pronounced effects is predicted at northern latitudes for both freshwater and marine aquatic ecosystems. One consequence of warming in the north occur during winter since decreasing ice sheets will influence light irradiation and spectral quality, an increase in precipitation is also predicted to increase the level of dissolved organic matter (DOM) leading to ocean and lake brownification.

The first full winter mesocosm experiment in arctic like conditions will be performed between November 2021 to May 2022. Nine Ice-resistant mesocosms developed within the AQUACOSM project will be deployed within AQUACOSM-plus WP8 task 8.4 at sub-Arctic ice conditions in the northern Baltic Sea. In addition, nine indoor mesocosms with ice capability will be used simultaneously to compare out and indoor mesocosm experiments. The project aims to investigate the influence of an increase in DOM by adding extracts of natural organic carbon of two different origins.

Researchers are welcome to take part in this experiment through the Transnational Access (TA) programme within AQUACOSM-plus. Applicants can be experts, trainees, or groups, as explained at: https://www.aquacosm.eu/transnational-access/aquacosm-plus/

Deadline for TA application at MF-UMSC is 30 April 2021, 13:00 CET.

AQUACOSM (call closed)

The Mesocosm Facility at Umeå Marine Sciences Center (MF-UMSC) has no opening for new TA applicants in 2021 in the frame of AQUACOSM. The projects planned in 2020 (see Opening for Transnational Access in 2020) were postponed to 2021 with already approved TA applicants who will be offered TA until end of July 2021.

Our Mesocosm Facility at Umeå Marine Sciences Center (MF-UMSC) is closed from January to February 2020 since we will update the computer and software that manage temperature control. 

We will have a project on our own in March 2020 and have open vacancies for people funded by TA to join, further information on the project below (Mesocosm Experiment in March 2020).

April-May 2020 and August-October 2020 is open for TA applicants who want to test their own scientific ideas and design their own project.

We have at least 230 user days left for Transnational Access in 2020, projects that make use of the unique ice capability of the facility are especially interesting.

Contact: Henrik Larsson for questions regarding the facility.

Mesocosm Experiment in March 2020:

Procaryotic maintenence respiration, activities and structural adaptationat low temperature and starvation in the sub-Arctic (PROMAC).

Project lead: Johan Wikner.

Timing: March proir to the sub-Arctic spring bloom peak.

The mesocosm experiment in March 2020 aims to impose high and low specific bacterial growth rate by temperature (1 and 10 °C), and with or without amendment of DOM (likely yeast extract + 30 % of natural DOC and mineral nutrients). A full factorial experiment with interaction of these factors using triplicates of each treatment will be applied. Our group will measure bacterial respiration, growth and abundance, including samples for bacterial taxonomy, gene expression and electron microscopy. Colleagues with interest in these treatments measuring other variables are kindly invited to apply to TA and if successful participate.

The MF-UMSC facility opens from mid January 2019 to December 2019. We announce open time slots for different types of mesocosm experiments in 2019. Projects can make use of the unique features of the mesocosms, including controlled convective stirring and stratification on the basis of temperature and/or salinity. The facility has now been further upgraded in order to harbor projects that includes freezing or thawing of ice at the water surface, which also allows for systematic seeding experiments. The new light sources are time controlled with near perfect spectra and intensity any time of year and any time of day. The ventilation ensures a natural CO2 concentration in the room, allowing for controls in studies focusing on the impact of an increased carbon dioxide content in the water. The facility is open all year around, and WP6 projects have highest priority.

Some topics fits ongoing research at UMU, and projects can benefit from available local expertise. Even if we keep the topic open in general we prefer topics related to the research profile of our university. Examples of such topics are: – Land-sea interactions, including effects of dissolved organic matter, nutrients, metals and freshwater on the coastal zone. – Climate change scenarios testing for effects of temperature, changed hydrography (stratification, turbulence and mixing) on biology and chemistry. Transformation and propagation of Mercury, other metals, persistent organic pollutants and pharmaceuticals and their effect on the food web are also preferred themes. However, such projects require permission and/or equipment to get rid of the toxic substances, which mean that we cannot guarantee forehand that any such project can be performed. Studied objects are primarily part of the water column such as plankton, their biodiversity and major associated processes. However, mysids, smaller fish and natural bottom sediments can also be introduced in the mesocosms and subject to study.

There´s currently no need for specific expertise/instrumentation. It will depend on what the specific project requires. We are open to both brackish water, marine and freshwater scientists from all disciplines.

MF-UMSC offers open access to all infrastructure in the MF-UMSC for visiting scientists accepted through AQUACOSM TA activities. At least 280 person days for TA will be allocated to external users in 2019. We aim for 2 projects in 2019 with 4-8 participants. Visiting scientists can work on independent projects for up to 30 days, with the mesocosm hall and adjacent laboratories exclusively reserved. In addition, smaller groups are welcome to join other projects at MF-UMSC at any time.

The MF-UMSC facility opens from January 2018 to December 2018. We announce open time slots for different types of mesocosm experiments in 2018. It is an advantage from our point of view if projects can make use of the unique features of the mesocosms (e.g. control of stratification and turbulence). Note that the ice capability will not be accessibly until the second half of 2018. The facility is open all year around, and WP-6 projects has highest priority.

There are also some topics that fits ongoing research at UMU. Such projects can benefit from available local expertise. Even if we keep the topic open in general we prefer topics related to the research profile of our university. Examples of such topics are: – Land-sea interactions, including effects of dissolved organic matter, nutrients, metals and freshwater on the coastal zone. – Climate change scenarios testing for effects of temperature, changed hydrography (stratification, turbulence and mixing) on biology and chemistry. This may from autumn 2018 include effects of ice cover. Transformation and propagation of Mercury, other metals, persistent organic pollutants and pharmaceuticals and their effect on the food web are also preferred themes. However, such projects require permission and/or equipment to get rid of the substances, which mean that we cannot guarantee that any such project can be performed.

MF-UMSC offers open access to all infrastructure in the MF-UMSC for visiting scientists accepted through AQUACOSM TA activities. At least 208 person days for TA will be allocated to external users in 2018. We aim for 1-2 projects in 2018 with 4-8 participants. Visiting scientists can work on independent projects for up to 30 days, with the mesocosm hall and adjacent laboratory exclusively reserved for AQUACOSM. In addition, smaller groups are welcome to join other projects at MF-UMSC at any time.

Description of the Infrastructure

Description of the infrastructure: The Mesocosm Facility at Umeå Marine Sciences Center (MF-UMSC) has an indoor and an outdoor component. It is located close to the seashore in the northern part of the brackish Baltic Sea (63 °N latitude). The indoor facility consists of 12 cylindrical mesocosms with water columns 4.86 m high and 0.74 m in diameter (volume ca. 2 m3). Temperature can be controlled and manipulated in 3 different sections of each mesocosm. This enables projects that require stratification, controlled convective stirring or both. Projects that require ice can be carried out, and parameters such as freezing or thawing rate can be adjusted. Valoya R-258 (Light DNA) are used as a light source, especially produced with the aim to closely mimic the spectra of the sun. The intake water can either be pumped in directly from the sea or be supplied from elsewhere. Equipment is available for studies requiring intact sediment in the mesocosms. This includes a semi-automatic sediment sampler. The indoor mesocosms are equipped with filters of different mesh sizes, down to 1 μm, and an automatic water renewal system to control turnover rates. The newly established outdoor facility is available during summer. It consists of 4 large pools with temperature-controlled running seawater, each carrying 6 cubic mesocosms of 1 m3 (Fig.9.7 right). Experimental designs can be supported by long-term local time series of ecological variables stored in an easily accessible database on the internet. The facilities can also be used for freshwater studies by running experiments with water from the nearby Öre River.

MF-UMSC is equipped with modern wet and dry labs, several special laboratories, 2 large aquarium halls, 5 walk-in cold rooms, and seagoing research vessels as well as small boats. Various analytical instruments for chemical and biological analyses are available. An auditorium for 50 persons and a classroom laboratory are also available. The direct connection of MF-UMSC with the Departments of Ecology and Environmental Sciences, Chemistry, and Molecular Biology ensures access to additional analytical facilities in environmental and analytical chemistry and molecular biology, as well as expertise of a broad scientific community.
