  1. 1. IDENTIFICATION OF ENVIRONMENTALLY RELEVANT BENTHIC FORAMINIFERA FROM THE SKAGERRAK FJORDS BY DEEP LEARNING IMAGE MODELING

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Marko Plavetic; [2023-06-26]
    Keywords : benthic foraminifera; deep learning; environmental monitoring; YOLOv7;

    Abstract : Over the several past decades, there has been increasing interest in using foraminifera as environmental indicators for coastal marine environments. As compared to macrofauna, which are currently used in environmental studies, foraminifera offer several distinct advantages as bioindicators, including short generation times, a high number of individuals per small sample volume, hard and durable tests with high preservation potential, and low cost of sample extraction.

  3. 2. Influence of different carbon sources on methane fluxes in sediments of eelgrass beds and unvegetated areas: a case study on the Swedish west coast

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Hampus Holmberg; [2023-06-22]
    Keywords : ;

    Abstract : One of the best ways to mitigate climate change is through natural carbon sequestration. An efficient way to mitigate climate change is through carbon sequestration from coastal habitats. READ MORE

  4. 3. Response of foraminifera Ammonia confertitesta (T6) to ocean acidification, warming, and deoxygenation - An experimental approach

    University essay from Lunds universitet/Geologiska institutionen

    Author : Elsa Muller; [2023]
    Keywords : Acidification; Warming; Deoxygenation; Foraminifera; Ammonia confertitesta T6 ; Culture Experiment; Trace elements; Earth and Environmental Sciences;

    Abstract : Ocean acidification, warmer temperatures, and the expansion of hypoxic zones in coastal areas are direct consequences of the increase in anthropogenic activities. However, so far, the combined effects of these stressors on calcium carbonate-secreting marine microorganisms - foraminifera are complex and poorly understood. READ MORE

  5. 4. Fluctuating pH simulating natural variability modulates larval growth for Strongylocentrotus droebachiensis

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Bryn Anderson; [2022-08-05]
    Keywords : ocean acidification; global change; sea urchin; duration; intensity; biological response;

    Abstract : Ocean acidification (OA) is the downward trend of ocean pH mainly resulting from the absorption of carbon dioxide (CO2) emissions from anthropogenic sources. pH of the open ocean is expected to drop to 7.7 by the end of the century. READ MORE

  6. 5. Using calcein-filled osmotic pumps to study the calcification response of benthic foraminifera to induced hypoxia under in situ conditions : an experimental approach

    University essay from Lunds universitet/Geologiska institutionen

    Author : Susanne Landgren; [2015]
    Keywords : benthic foraminifera; calcein; osmotic pump; hypoxia; Gullmar Fjord; bentiska foraminiferer; kalcein; osmotisk pump; syrebrist; Gullmarn; Earth and Environmental Sciences;

    Abstract : Bentiska foraminiferer används i stor utsträckning för miljöövervakning, t ex i kontext med syrebrist i kustnära vatten, vilket är det snabbast växande och mest allvarliga hotet mot marina ekosystem. Ett flertal studier har visat att många foraminiferarter har förmåga till överlevnad, förökning och biomineralisering under förhållanden med syrebrist (hypoxi) och till och med under helt syrefria förhållanden (anoxi).
