Quality controlled dissolved, inorganic nitrate+nitrite concentration data [µmol l^-1] collected in the Pemba Channel/Indian Ocean (Tanzania) in July 2019

A quality-controlled dataset of dissolved, inorganic nitrate+nitrite (NOx) concentrations [µmol l^-1] collected in the Pemba Channel/Indian Ocean (Tanzania) in July 2019 is presented here. The data were collected by a microfluidic lab-on-chip nutrient sensor (s/n 118) that was integrated into a buoyancy driven Kongsberg M1 Seaglider (s/n sg550, doi.org/10/hgvx). The ocean glider was deployed at varying positions within the Pemba Channel for daily missions on the 2nd-5th and 7th-8th July 2019. The nutrient sensor was set to sample at various time and depth intervals during the glider's deployment. NOx concentration data were collected between the 2nd-5th and 7th-8th July 2019. The location data (latitude, longitude, depth) provided in this dataset originate from the ocean glider data and were derived by linear interpolation onto the nutrient sensor time stamps. These data were collected as part of the Sustainable Oceans, Livelihoods and food Security Through Increased Capacity in Ecosystem research in the Western Indian Ocean (SOLSTICE-WIO) project (Global Challenges Research Fund under NERC grant NE/P021050/1), which aimed to investigate ecosystem health and resilience in the face of climate change in the Western Indian Ocean.
