Accumulated fine grained anthropogenic mud entrained in complex organic flocs is easily resuspended with even moderate wind events. The light environment is critical in governing harmful algal blooms as well as submerged aquatic vegetation. However, little is known regarding effects of sediment interstitial colored-dissolved organic matter (CDOM) delivered during resuspension events or simple diffusive inputs. Using a novel autonomous benthic lander, this study directly measured hyperspectral sediment-derived CDOM (SDCDOM) fluxes by conducting seasonal in situ benthic chamber incubations. On seven events, two short parcels of water were incubated in contact with sediments for periods of 6-8 hours to isolate effects due to sediment respiration and combined respiration\/photosynthesis, respectively. The chambers were sampled hourly via an autonomous syringe sampling system to determine the relative rate of accumulation or depletion of CDOM (measured hyperspectrally), dissolved organic carbon (DOC), and dissolved iron (Fed). For all collected syringe samples, these three analytes were highly correlated; however, dissolved iron was the primary predictor of DOC. With respect to calculated fluxes, the intensity of the SDCDOM flux was seasonally dependent, with greater fluxes in warm periods likely due to enhanced sediment anaerobic respiration (i.e. iron mineral solubilization and organic complexation). These seasonal disparities suggest that empirical remote sensing algorithms in Fe-rich inland waters should explicitly consider iron, either measured or modeled, when generating CDOM products.<\/p>\n *Hanna Bridgham<\/a><\/strong>, FAU Harbor Branch Oceanographic Institute, hbridgham2021@fau.edu, 0000-0003-4659-0694<\/p>\n Jordon Beckler, FAU Harbor Branch Oceanographic Institute, jbeckler@fau.edu<\/p>\n Mason Thackston, FAU Harbor Branch Oceanographic Institute, mthackston2021@fau.edu<\/p>\n Lynn Wilking, FAU Harbor Branch Oceanographic Institute, lwilking@fau.edu<\/p>\n Veronica Ruiz-Xomchuk, FAU Harbor Branch Oceanographic Institute, VRuiz-Xomchuk@fau.edu<\/p>\n Owen Silvera, FAU Harbor Branch Oceanographic Institute, OSilvera2021@fau.edu<\/p>\n Tim Moore, FAU Harbor Branch Oceanographic Institute, TMoore@fau.edu<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ custom_padding_last_edited=”on|tablet” _builder_version=”4.14.7″ _module_preset=”default” background_enable_color=”off” background_image=”https:\/\/oceanopticsconference.org\/wp-content\/uploads\/2022\/01\/oo22-banner-bckd.jpg” custom_padding=”0px||11px||false|false” custom_padding_tablet=”0px||11px||false|false” custom_padding_phone=”||27px||false|false” global_module=”2766″ saved_tabs=”all” locked=”off” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_row _builder_version=”4.16″ _module_preset=”default” custom_padding=”0px||8px||false|false” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_social_media_follow use_icon_font_size=”on” icon_font_size=”19px” _builder_version=”4.16″ _module_preset=”default” custom_button=”on” text_orientation=”right” custom_margin=”-10px||11px||false|false” custom_margin_tablet=”-9px||5px||false|false” custom_margin_phone=”-9px||5px||false|false” custom_margin_last_edited=”on|tablet” global_colors_info=”{}” button_text_size__hover_enabled=”on|desktop” theme_builder_area=”post_content”][et_pb_social_media_follow_network social_network=”facebook” url=”https:\/\/www.facebook.com\/OceanOpticsConference\/” _builder_version=”4.16″ _module_preset=”default” background_color=”#9b9b9b” background_enable_color=”on” global_colors_info=”{}” background__hover_enabled=”on|hover” background_color__hover=”#0C71C3″ background_enable_color__hover=”on” theme_builder_area=”post_content” follow_button=”off” url_new_window=”on”]facebook[\/et_pb_social_media_follow_network][et_pb_social_media_follow_network social_network=”twitter” url=”https:\/\/twitter.com\/OceanOpticsConf” _builder_version=”4.16″ _module_preset=”default” background_color=”#9b9b9b” background_enable_color=”on” global_colors_info=”{}” background__hover_enabled=”on|hover” background_color__hover=”#0C71C3″ background_enable_color__hover=”on” theme_builder_area=”post_content” follow_button=”off” url_new_window=”on”]twitter[\/et_pb_social_media_follow_network][\/et_pb_social_media_follow][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_3,1_3,1_3″ use_custom_gutter=”on” gutter_width=”2″ _builder_version=”4.16″ _module_preset=”default” custom_padding=”13px||34px|0px||” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”1_3″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.16″ _module_preset=”default” header_font_size=”26px” header_2_font=”|||on|||||” header_2_text_align=”center” header_2_text_color=”#FFFFFF” header_2_font_size=”21px” text_orientation=”center” custom_margin=”||5px|||” global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.16″ _module_preset=”default” text_text_color=”#FFFFFF” link_font=”||||on||||” link_text_color=”#FFFFFF” header_2_text_color=”#FFFFFF” max_width=”300px” module_alignment=”center” custom_margin=”||||false|false” custom_margin_tablet=”||-3px||false|false” custom_margin_phone=”” custom_margin_last_edited=”on|tablet” custom_padding_tablet=”||||false|false” custom_padding_phone=”||32px||false|false” custom_padding_last_edited=”on|phone” global_colors_info=”{}” link_text_color__hover_enabled=”on|hover” link_text_color__hover=”#a8a8a8″ theme_builder_area=”post_content”]<\/p>\n Sign up to receive email updates to be sure to catch all the meeting news.
