Aim Variation in species composition among locations (β‐diversity) is of fundamental interest in ecology, yet its dependence on spatial extent and grain has rarely been assessed empirically. This study provides a systematic empirical test of the spatial scaling of β‐diversity and highlights the importance of study design for detecting the role of environmental filtering in shaping regional β‐diversity. Location Northeastern Ch...

The strong CO 2 sink in Arctic Ocean plays a significant role in the global carbon budget. As a high-latitude oceanic ecosystem, the features of sea surface p CO 2 and air-sea CO 2 flux are significantly influenced by sea ice melt; however, our understanding of p CO 2 evolution during sea ice melt remains limited. In this study, we investigate the dynamics of p CO 2 during the progression of sea ice melt in the western Arctic...

Oceanic uptake of anthropogenic CO 2 causes a decrease in seawater pH and aragonite saturation state (Ω arag ), a process known as ocean acidification (OA). The western North Pacific is a hotspot for anthropogenic CO 2 sinks; however, the spatiotemporal variability of pH and Ω arag and their controlling mechanisms remain unexplored. In this study, we provide high-frequency and high-precision underway measurements of sea surfac...
