We examine benthic foraminiferal communities along an inner-to-outer transect in a fjord of Victoria Land. Community structure reflects organic matter flux, sedimentation rates, and circulation regimes. Inner sites show signs of stress, likely tied to oxygen depletion after sea-ice break up. Outer sites have higher densities, suggesting improved conditions. Comparison between paleocommunities and modern assemblages shows that communities are still recovering from late Holocene changes.

Groundwater is rapidly being depleted in many regions, threatening water security and food production. We studied a major groundwater depression in northern China to test whether recharging aquifers with diverted river water can help recovery. Using long-term computer simulations, we found that recharge raises water levels and dilutes nitrate pollution, offering an effective way to restore overused aquifers.
