Founded in the year 2002, AquaEcology has al­ready been part of sev­eral scien­tific proj­ects. With­in this frame, plank­ton and nu­tri­ent anal­yses have been car­ried out and ex­pert's re­ports been com­piled. The insti­tute also par­tici­pates in the set­ting-up of bio­logical and chemi­cal as­sess­ment sys­tems. The refer­ence list of the con­tract re­search gives an over­view over these ac­tiv­ities in the re­cent past.

Im­por­tant fields within this work are the optimi­sation of meth­ods and qual­ity as­sur­ance mea­sures. All used meth­ods are in ac­cor­dance with inter­national stan­dards and regu­larly vali­dated by inter­cali­bration ex­er­cises and inter­labo­ratory com­pari­sons. On request, ev­ery cus­tomer will re­ceive the re­spec­tive trans­parent docu­men­tations. By this, AquaEcology en­sures the high qual­ity of its ana­lyt­ical work. Ac­credi­tation ac­cording to DIN EN ISO/IEC 17025 will be ap­plied for in co-op­era­tion with the BLMP qual­ity as­sur­ance centre of the German Fed­eral En­viron­ment Min­istry.

The man­ag­ing di­rec­tors of AquaEcology, the certi­fied biol­ogist Dr. Claus-Dieter Dürselen and the certi­fied chem­ist Thomas Raabe, worked for many years as scien­tists in the fields of ma­rine biol­ogy and ma­rine chem­istry at the uni­versi­ties of Olden­burg and Ham­burg. But also the other col­leagues in the insti­tute have got sub­stan­tial ex­peri­ence in aquat­ic ecol­ogy as biol­ogists, geol­ogists and as ex­perts in bio­infor­matics. By work­ing in var­ious na­tional and inter­na­tional co-opera­tions they have gained the nec­es­sary com­pe­tence for co-ordi­nating and con­ducting inter­na­tional proj­ects and ex­peri­ments. In the fol­low­ing, you will find a short over­view over the proj­ects where per­son­nel of AquaEcology have worked as scien­tists, very often being in re­spon­sible po­si­tion. With­in this con­text, they were en­gaged in the planning and real­isa­tion of the ex­peri­ments, in­clu­sive of sample processing, anal­ysis, eval­uation and publi­cation of the scien­tif­ic data.

Further­more, all scien­tists of AquaEcology con­trib­ute to inter­na­tional pub­lica­tions and reg­ular­ly par­tici­pate in scien­tific sym­po­sia and work­shops.

Quality assurance

For quality assurance reasons, AquaEcology regu­larly par­tici­pates in inter­labo­ra­tory com­pari­sons, inter­cali­bra­tion ex­er­cises and taxo­nomic work­shops. Further­more, the in­sti­tute is going to get ac­cred­ited for the bio­log­ical and chem­ical anal­ysis fol­lowing DIN EN ISO/IEC 17025. AquaEcology co-operates with the work­ing group 'biol­ogy' of the qual­ity as­sur­ance centre of the Ger­man Fed­eral En­viron­ment Min­istry.
