The Eugen Seibold is a seaworthy sailing yacht that was specially developed and built for the contamination-free collection and analysis of seawater , plankton and air samples. Since the end of 2018, the research vessel for science in use to the interactions between ocean and atmosphere to investigate. The operator is the Max Planck Institute for Chemistry in Mainz . It is named after the German marine geologist Eugen Seibold (1918–2013).
history
The aim of this new ship development is to react more flexibly and dynamically to environmental and climate events and to be able to research them at short notice. For example, with the help of the sailing yacht Eugen Seibold, phenomena such as El Niño or the long-range effects of dust storms and large bush and forest fires can now be quickly incorporated into the expedition program and examined. These short-term assignments complement the long-term research program in which stations are sampled regularly over a period of several years. The small size and a sustainable operating concept should enable very economical research. The construction of the ship with a hull made of fiberglass-reinforced plastic and battery operation for up to nine hours enables water and air to be sampled that have not been contaminated by exhaust gases or rust from the research vessel itself.
Lorenzo Argento Yacht Design ( Italy ) carried out the construction. The implementation was carried out by Michael Schmidt Yachtbau in Greifswald . The architects Axthelm & Rolvien (Berlin) were responsible for the interior design. A transmission was developed together with ZF Friedrichshafen . In collaboration between Hydrobios ( Kiel ) and the mechanical workshop of the Max Planck Institute for Chemistry, a multi-locking net made of titanium was manufactured. The Werner Siemens Foundation financed the construction of the yacht with 3.5 million euros.
Construction of the yacht began in 2017. On May 11, 2018, Ilse Seibold christened the ship in Kiel as part of a festive symposium in honor of her deceased husband. The sailing yacht is looked after by the shipping company F. Laeisz , the home port is Funchal on Madeira , so the ship carries the Portuguese flag . It is owned by the Zurich- based non-profit foundation research ship Eugen Seibold , which is maintained by the Max Planck Society .
The research yacht Eugen Seibold is to sample all climatic zones and the various marine areas. In 2019 she embarked on a transect planned until 2021 from the tropical to the polar North Atlantic and across the Caribbean to the Eastern Pacific .
equipment
The sailing yacht of the Explorer 72 model is 22 meters long, 6 meters wide and has a draft of 3.5 meters. The 44-ton ship reaches a speed of 8-10 knots with a sail area of 350 m² in sloping rigging . It fulfills category A of the CE seaworthiness rating . There are eight berths on board for four to six scientists and two to four crew members. With a 4000 liter diesel tank, 1000 liters of fresh water and a seawater desalination system , the research yacht is autonomous for up to three weeks. The yacht has electric motors and lithium iron phosphate batteries with a capacity of around 65 kWh, with which research can be carried out for up to 9 hours without emissions. A 288 volt generator with 67 hp provides the electrical energy supply . The batteries can be charged via the wave generator from a speed of 3 kn . The research sailor also has a nearly 210 hp six-cylinder diesel engine.
Half of the interior is occupied by three laboratories, in which samples can be evaluated on site. The sample water is pumped into the wet laboratory from a depth of three meters through a Teflon pipe in the keel . It is equipped with instruments for chlorophyll -, particulates and carbon dioxide - analytics , for bacterioplankton analysis and for analysis of the primary production equipped. It also contains filtration equipment , a safety workbench (clean bench), an extractor hood, and refrigerators and freezers . The devices in the semi-wet laboratory can be used to analyze carbon dioxide isotopes and quantify the argon - oxygen ratio to determine primary production. Sample air is sucked in about ten meters above the deck and analyzed in the air laboratory. The laboratory is equipped with analytics for atmospheric particles. Number concentrations, size spectra and microphysical properties of particles such as aerosols and soot are measured directly. All particles are collected on filters and prepared for further analysis.
At the stern is a hydraulic stern boom that can be used to pick up and deploy equipment. The deeper water column is sampled with a CTD rosette , in-situ filtration, multi-locking net, bongo net and sediment trap. Parameters such as water temperature , salinity , pH value , oxygen content and fluorescence are permanently recorded at various positions in the water column. A sensor on the top of the mast registers the photosynthetically active radiation (PAR).
research
The Climate Geochemistry Department at the Max Planck Institute for Chemistry , headed by Gerald Haug , is investigating the role of the ocean in climate change with the help of S / Y Eugen Seibold . For this purpose, physical parameters such as temperature , biological aspects such as plankton occurrence and chemical parameters such as the concentration of oxygen , carbon dioxide , trace metals and salinity are recorded in the air and the upper water column . In addition to a detailed description of the state of the deeper atmosphere and the oceans, the new data will also be used to reconstruct past climatic conditions .
The investigations include both air samples and the euphotic zone , i.e. H. Light- flooded, productive upper water column and the twilight zone below, up to a depth of 1000 meters. Most of the chemical and biological degradation and exchange processes take place at the sea surface and the upper 1000 meters of the ocean. These processes have a significant influence on the distribution of greenhouse gases such as carbon dioxide in the earth's atmosphere and the ocean. Distribution and properties of atmospheric aerosols of continental and oceanic air masses influence the climate through various ocean-atmospheric exchange processes, cloud formation and radiative forcing .
