Along the WFS and adjacent coastal water bodies, inputs of organic nutrients from groundwater and rivers are thought to play a crucial role in the timing and extent of coastal algal blooms. Significant regional and seasonal variability of riverine sources has been well recognized. However, it remains unknown whether the composition of dissolved organic matter (DOM) in groundwater and river water discharged into the WFS is also variable. Identifying factors that differentiate DOM composition from different coastal inputs along the WFS is necessary to track its fate and impact on coastal ocean ecosystems and predict how changing hydrologic processes will impact the organic matter supply. To address this gap, we characterized and compared the molecular composition of solid-phase extracted DOM from submarine groundwater discharge (SGD) and river sources on the WFS across four seasons using ultra-high performance liquid chromatography-Orbitrap mass spectrometry (UHPLC-Orbitrap-MS). SGD stations include Nature Coast, Indian Rock Beach, and Venice Headlands well stations. River stations include Hillsborough River, Alafia River, Manatee River, Peace River, and Caloosahatchee River stations. Samples were collected quarterly. Specifically, SGD samples were collected in November 2022, February 2023, June 2023, and September 2023. River samples were collected in November 2022, February 2023, May 2023, and August 2023.\n\ncdm_data_type = Other\nVARIABLES:\ntime_point (Time, minutes)\nMolecular_Formula (unitless)\nCalculated_m_z (m/z)\nm_z (m/z)\nm_z_Error_ppm (m/z)\nCalibrated_m_z (m/z)\nIntensity_CH_250617_SGDRIVER_20250617_pooled_117 (counts per second (CPS))\nIntensity_CH_250617_SGDRIVER_20250617_pooled_117_n56 (counts per second (CPS))\nIntensity_CH_250617_SGDRIVER_20250617_pooled_3_n3 (counts per second (CPS))\nIntensity_CH_250617_SGDRIVER_20250617_pooled_66_n13 (counts per second (CPS))\nIntensity_CH_250617_SGDRIVER_AR1_AUG_38_n40 (counts per second (CPS))\n...
