The marine dissolved organic carbon (DOC) pool is an important player in the functioning of ecosystems. DOC at interface between chemical and biological worlds, it fuels food webs, a major component Earth's system. Here, we review research showing impacts global change stressors on cycling, specifically: ocean warming stratification, acidification, deoxygenation, glacial sea ice melting, changed inflow from rivers, changing circulation upwelling, wet/dry deposition. A unified outcome future...
Abstract The bioavailability of organic matter (OM) was assessed at three locations during the dry and wet seasons in Great Barrier Reef (GBR), by measuring changes particulate (POM) dissolved (DOM) concentrations laboratory incubations over 50 d. sites did not show any difference salinity and, therefore, observed could be related to factors such as disparities biological activity and/or impact sediment resuspension rather than location. Our results demonstrate that POM pool has a higher DOM...
Abstract. Measurements of dissolved organic carbon (DOC), nitrogen (DON), and phosphorus (DOP) concentrations are used to characterize the matter (DOM) pool important components biogeochemical cycling in coastal ocean. Here, we present first edition a global database (CoastDOM v1; available at https://doi.org/10.1594/PANGAEA.964012, Lønborg et al., 2023) compiling previously published unpublished measurements DOC, DON, DOP waters.

Abstract Tett, P., Carreira, C., Mills, D. K., van Leeuwen, S., Foden, J., Bresnan, E., and Gowen, R. J. 2008. Use of a Phytoplankton Community Index to assess the health coastal waters. – ICES Journal Marine Science, 65: 1475–1482. Monitoring marine-ecosystem status requires indicators community structure function. As structural indicator, we propose (PCI) based on abundance “life-forms” such as “pelagic diatoms” or “medium-sized autotrophic dinoflagellates”. To calculate PCI, data showing...
The syndrome Amnesic Shellfish Poisoning (ASP) results from ingesting sea food contaminated by a neurotoxin, domoic acid. Diatoms of the genera Pseudo-nitzschia and Nitzschia are responsible for production this toxin. A total eleven species were identified during two plankton surveys at entrance in southern channels Ria de Aveiro, largest lagoon on west coast Portugal. During first survey, conducted February to October 2000, following identified: P. australis, cuspidata, delicatissima,...
Viral abundances in benthic environments are the highest found aquatic systems. Photosynthetic microbial mats represent with high activity and possibly viral densities, yet have not been examined such Existing extraction procedures typically used ecology were applied to complex matrix of but inefficiently extract viruses. Here, we present a method for quantification viruses from photosynthetic using epifluorescence microscopy (EFM) flow cytometry (FCM). A combination EDTA addition, probe...
Global change impacts on marine biogeochemistry will be partly mediated by heterotrophic bacteria. Besides ocean warming, future environmental changes have been suggested to affect the quantity and quality of organic matter available for bacterial growth. However, it is yet determined in what way warming changing substrate conditions impact bacteria activity. Using short-term (4 days) experiments conducted at 3 temperatures (-3°C, situ, +3°C) we assessed temperature dependence cycling...
Compared to higher latitudes, tropical heterotrophic bacteria may be less responsive warming because of strong bottom-up control. In order separate both drivers, we determined the growth responses bacterial physiological groups temperature after adding dissolved organic matter (DOM) from mangroves, seagrasses and glucose natural seawater Great Barrier Reef.

Abstract Dissolved organic carbon (DOC) in coastal waters is integral to biogeochemical cycling, but global and regional drivers of DOC are still uncertain. In this study we explored spatial temporal differences concentrations stocks across the ocean, how these relate temperature salinity. We estimated a median stock 3.15 Pg C (interquartile range (IQR) = 0.85 C), with being 2.2 times higher than open ocean surface waters. Globally seasonally, salinity was main driver correlated negatively...

Abstract Scientists who are skilled in communication reap professional and personal rewards. Unfortunately, gaps exist fostering curricular extracurricular training science communication. We focus our article on opportunities for university‐ department‐level leadership to train new scientists communicate effectively. Our motivation is threefold: (1) key being competitive the increasingly diverse job market, (2) early career “jump‐starts” societal benefits, (3) authors represent a group of...

Microbial mats are compacted, surface-associated microbial ecosystems reminiscent of the first living communities on early Earth. While often considered predominantly prokaryotic, recent findings show that both fungi and viruses ubiquitous in mats, albeit their functional roles remain unknown. Fungal research has mostly focused terrestrial freshwater where known as important recyclers organic matter, whereas exceptionally abundant aquatic ecosystems. Here, have shown to affect matter cycling...

Abstract Observation of benthic photoautotrophs on sediment surfaces shows a single algal layer without distinction between photosynthetic groups. Until now it has not been possible to distinguish microorganisms, i.e. cyanobacteria and diatoms, at μ m mm scales using nondisruptive system. Chlorophyll autofluorescence can be used different photoautotrophic groups if the correct excitation light is applied. Using this principle, nonintrusive technique was developed study spatial distribution...
