Since 2006 GiMaRIS specialises in marine research, inventory, & strategy solutions focusing on consultancy next to international monitoring projects and rapid assessments in temperate Atlantic and in Indo-Pacific waters. More recently marine invasive species projects have been the main focus because of the dramatically increasing impact that these species have had on temperate water ecosystems around the world. Substantial ecological and economical damage has been caused by the introduction of invasive marine species and their diseases, parasites, and predators. These invaders can e.g. threaten public health, be a great nuisance for tourists, and cause substantial damage to aquacultural organisations and other companies as fouling organisms that overgrow shellfish, boats, floating docks and sluices, or hamper through-flow within pipes and water channels.
The additive value of GiMaRIS becomes most apparent in projects in which correct species identifications are of the uttermost importance. Misidentifications and incomplete biodiversity assays have caused companies to unwillingly and unknowingly take unnecessary high risks when applying for tenders or when proceeding with their maritime activities and constructions. Vice versa, risks may be much lower than expected when for example so-called endangered species turn out to be invasive species or when they are known for a preference for disturbed environments. Natural regeneration mechanisms that depend on certain species being present, play a critical role in the vulnerability of ecosystems and their ability to restore after a disturbance. In support of fieldwork research, the GiMaRIS laboratory that was opened May 2008 in the Leiden BioScience Park, enables aquarium studies and molecular analyses to be done instantly.
Fundamental research and public education form an important part of GiMaRIS. Over the years the fundamental research at and for GiMaRIS has mostly been done by students from the studies Biology (Institute of Biology, Leiden University), BioInformatics (Leiden University of Applied Sciences), Molecular diagnostics (TOPlab, Leiden University of Applied Sciences), Coastal Zone Management (Van Hall Larenstein University of Applied Sciences, Leeuwarden, part of Wageningen University and Research Centre), Aquatic Ecotechnology (HZ University of Applied Sciences, Vlissingen), and Forestry and Nature Management (Helicon Velp). To stay in touch with the scientific community, industry, politicians and the general public, research results are published through a variety of media including the worldwide web, newspapers, governmental reports, popular scientific magazines and SCI-journals. The multidisciplinary research projects of GiMaRIS involve, mostly in cooperation with other SMEs like MatureDevelopment, Maad Advies and TPS, theoretical methodology development, invasive species risk assessments, short and long term marine monitoring projects, and consultancy for the purpose of providing marine research, inventory, & strategy solutions according to the People-Planet-Profit philosophy.
The founder of GiMaRIS, Dr. A. Gittenberger, has worked for e.g. the national natural history museums of The Netherlands (Naturalis), France (MNHN), and the USA (Smithsonian), for National Geographic magazine (USA), AtosOrigin, Expert Centre of Taxonomic Identification (ETI), The ANEMOON Foundation, the Netherlands Central Bureau of Statistics, and in the EU Networks MARBEF, BIOCOMBE, EDIT, Green Spider Network, WORMS, and FRONTIERS. The company’s clients include the Dutch Ministry of Transport, Public Works and Water Management; the Dutch Ministry of Agriculture, Nature and Food Quality; The European Shellfish industry; CABI; IMARES Institute for Marine Resources & Ecosystem Studies; the Dutch Institute for Delta Technology Deltares, and the marine research institutes of the European MarPACE project that is coordinated by the Netherlands Institute of Sea Research (NIOZ). In addition GiMaRIS aims at studying biodiversity patterns with marine and brackish water from a holistic point of view by actively working and cooperating with MESA+, Institute for Nano-technology, Twente University; the Center for Functional Nanostructures, University of Karlsruhe; the Netherlands Agency for Aerospace Programmes; the Institute of Biology, Leiden University; the University of Applied Sciences Leiden; the Coastal Zone Management study, Van Hall Institute, Leeuwarden; and the SMEs TPS and MatureDevelopment.

-June 2010: Expedition Doggersbank. Eleven highly experienced divers, each with their own unique specialism, will join forces to investigate the marine biodiversity present in and around wrecks at the Doggersbank, North Sea. While some team members will focus on removing lost fishing gear from the wrecks to prevent ghost fishing, others will use their professional video and photography skills to raise public awareness and show that this remote area needs to be protected (e.g. as a Natura2000 site). Rapid assessments of all living organisms, coordinated by a group of marine biologists, will further strengthen the value of these images and videos in order to convince politicians and the general public that wrecks form the most precious and species rich marine ecosystems, offshore in the North Sea.

* Genome sequencing of Didemnum vexillum
*
Ascidian habitats in harbors
*
Ascidians in the succession of fouling communities
* Settlement, spread, seasonality, and succession of native and non-native Botryllidae in The Netherlands

Some of these species like Botrylloides violaceus, which is introduced from the NW Pacific, are very brightly coloured:
