Shifts in microbial metabolism for algal-derived organic matter utilization under dynamic oxygen conditions
1.Introduction: As human activities intensify, declining ocean oxygen has resulted in widespread hypoxia in coastal and open-ocean regions. Hypoxia is typically defined as dissolved oxygen (DO) concentrations below 63 μM (2 mg/L)(Diaz and Rosenberg, ...

Suppression of marine heatwave activity by tropical cyclone–induced upper ocean cooling
Iam-Fei Pun1*, I-I Lin2, Chun-Chieh Wu2Marine heatwaves (MHWs) have drawn substantial scientific attention due to their profound biological and eco- nomic impacts, especially in the context of climate change. This study highlights the crucial role of...

Sea surface warming and ocean-to-atmosphere
feedback driven by large-scale offshore wind farms under seasonally stratified conditionsHyodae Seo1,2*†, César Sauvage1,2†, Christoph Renkl2,3†,Julie K. Lundquist4,5†, Anthony Kirincich2†Offshore wind farms may induce changes in the upper ocean and near-surface atmosphere through coupled ocean- atmosphere feedbacks. Yet, the role of air...

Coastal bays serve as reservoirs for microplastics from East China: insights
from a mass budget model based on sedimentary findingsOver the past two decades, research and concern regarding micro- plastics (MPs, < 5 mm) in the marine environment have continued to escalate (Auta et al., 2017; Alimi et al., 2018; Rochman, 2018a). MPs can be either primary (originating from plast...

Environmental performance of blue foods
The food system is a major driver of environmental change, emittinga quarter of all greenhouse gas (GHG) emissions, occupying half of allice-freeland, and responsible for three quarters of global consumptivewater use and eutrophication3,6. Yet, it st...

Global methane emissions from rivers and streams
Freshwater ecosystems are responsible for nearly half of global CH4 emissions to the atmosphere4.7. Yet, among freshwaters, the role of rivers and streams in the global CH4 cycle remains unclear althoughcurrent best estimates of global fluvial emissi...

Combined effects of polyamide microplastics and the pathogenic bacterium
Vibrio parahaemolyticus on the immune parameters of Mytilus coruscusThe thick-shell mussel Mytilus coruscus is a crucial marine ecological indicator species, sensitive to environmental changes and pollution. Its population size, growth condition, and reproductive capacity serve as key indicators of the health of the ...
