WebAbstract. Biological nitrogen fixation plays an important role in the global nitrogen cycle. However, the fixation rate has been usually measured or estimated at a particular observational site. To quantify the fixation amount at the global scale, process-based models are needed. This study develops a biological nitrogen fixation model to quantitatively … WebJun 22, 2015 · Depth (Z 50) and thickness (H) of nitracline and phosphocline was determined following Hauss et al. by fitting sigmoid regressions of NO 3- and PO 43- concentrations as a function of depth down to 150 m [ 24 ].
WebSIP is able to provide a unique perspective into nutrient cycling because the identity of the organisms actively involved in the transformation of specific 15N-substrates is directly determined through the incorporation of the isotopically labeled N into their DNA (Cadisch et al., 2005; Buckley et al., 2008; Wawrik et al., 2009; Orsi et al., 2024).
