Bolding & Bruggeman

Bolding & Bruggeman (BB) is a Danish research and development company specializing in advanced numerical models for natural waters, particularly lakes and oceans. The company was established in 1999 in Varese, Italy, by Hans Burchard and Karsten Bolding under the name Bolding & Burchard ApS. The two founders were equal partners until autumn 2014, when Jorn Bruggeman replaced Hans Burchard, and the company was renamed Bolding & Bruggeman ApS. Today the firm is based in Asperup, Denmark, and operates as a private partnership. BB develops and applies numerical models for natural waters. Its work spans both public open-source software projects and applied research collaborations. The company is notably involved in GOTM (General Ocean Turbulence Model) and GETM (General Estuarine Transport Model), two widely used Fortran-based modeling frameworks, as well as its own open-source projects. The Fortran-based software is hosted on GitHub and requires a Fortran compiler to build, while Python-based projects are also available on GitHub and installable via pip, for example with the command `pip install pyncview`. Beyond software development, BB participates in a number of national and international research projects and also engages in more applied projects. The company states that it is always interested in potential collaboration opportunities. Its software is used throughout the world to support sustainable development as defined through the UN Global Goals. As a small, specialized R&D firm, Bolding & Bruggeman occupies a niche at the intersection of oceanography, limnology, and scientific software engineering. Its tools are used by researchers, environmental agencies, and consultants to simulate physical processes in lakes, estuaries, and coastal seas. The company's dual focus on open-source software and applied consulting allows it to bridge academic research and practical environmental management.

Bolding & Bruggeman was established in 1999 in Varese, Italy, by Hans Burchard and Karsten Bolding as Bolding & Burchard ApS. The two founders were equal partners in the venture, which focused on developing and applying advanced numerical models for natural waters. For roughly fifteen years the company operated under the Bolding & Burchard name, building a reputation in the oceanographic and limnological modeling community. In autumn 2014, the partnership changed: Jorn Bruggeman replaced Hans Burchard as a partner, and the company was renamed Bolding & Bruggeman ApS. The firm is now based in Asperup, Denmark, and continues to operate as a private partnership. Its core activities remain the development and application of numerical models for lakes and oceans. Over the years, BB has participated in a number of national and international research projects, as well as more applied projects. It has contributed to public software projects within the area of natural waters, notably GOTM and GETM, and maintains its own open-source projects. The Fortran-based software is available from GitHub and requires a working Fortran compiler, while Python-based projects are also hosted on GitHub and installable via pip (for example, `pip install pyncview`). The company emphasizes collaboration and states that it is always interested in hearing about potential collaboration options. Its software is used throughout the world to work towards sustainable development as defined through the UN Global Goals. As of the latest available information, BB remains an active, small-scale R&D company with a global user base for its modeling tools.
