Dissolved organic matter molecular composition data for multiple oceanographic cruises with RV SONNE (SO254, SO245, SO248) and RV POLARSTERN (PS79), Bermuda Atlantic Time-series Study and Hawaii Ocean Time-series


This data includes the dissolved organic matter (DOM) molecular composition data obtained via Fourier-transform ion cyclotron resonance mass spectrometry for multiple oceanographic cruises collected in the Atlantic, Pacific and Southern oceans (HOTS, BATS, SO254, SO245, SO248, ANT 28-II, ANT 28-IV, and 28-V) between 2009 and 2017. This analysis was conducted to assess the molecular composition of DOM in the context of ocean mixing. DOM was extracted and desalted using the solid phase extraction method as described in Dittmar et al. 2008. The extracts were stored frozen in methanol until analysis in 2019, when aliquots of the extracts were mixed with 50% ultrapure water (50:50 v/v) and diluted to a final carbon concentration of 2.5 ppm. DOM composition was determined on a SolariX XR FT-ICR-MS (Bruker Daltonik GmbH, Bremen, Germany) equipped with a 15 Tesla superconducting magnet and an electrospray ionization source (ESI; Bruker Apollo II ion source) in negative ion mode, as described in (Bercovici, Dittmar, and Niggemann 2022). Subsequent data processing and molecular formula assignment was conducted in ICBM-OCEAN, as described in (Merder et al. 2020).

The authors gratefully acknowledge Aron Stubbins, Natasha McDonald, and John Casey for collection of the HOTS and BATS samples.
