Significant Coastal Dune Loss Challenges California's Climate Resilience and Biodiversity Goals

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract Coastal sand dunes support unique biodiversity and buffer beaches and communities against storm impacts. However, these sensitive and dynamic ecosystems are increasingly threatened by erosion, sea‐level rise (SLR), and encroaching coastal development.

Seasonal succession and niche differentiation in Skeletonema species driven by temperature and salinity in inner Tokyo Bay

Journal of Phycology, Volume 62, Issue 3, Page 931-942, June 2026.
Abstract The genus Skeletonema is a dominant diatom in coastal waters worldwide, frequently causing blooms, and it includes several cryptic species. To elucidate the occurrence patterns and niche differentiation among Skeletonema species in Tokyo Bay, Japan, sampling was conducted between June 2021 and February 2023.

Ocean alkalinity enhancement in an estuary

Frontiers in Climate
A high-resolution numerical ocean model is used to assess ocean alkalinity enhancement (OAE) in the San Francisco Bay (SFB) estuary. A novel tracer-based approach is introduced to simulate alkalinity release and the subsequent CO2 ingassing. The model is
