Groundwater and Surface Water Interactions at the Tijuana Estuary, San Diego County, California - The Tijuana Estuary is a unique coastal plain and wetland-dominated estuary influenced by tidal fluctuations and saltwater inflow from the Pacific Ocean and by intermittent freshwater inflow from the Tijuana River. The lower Tijuana River valley, the alluvial river valley that leads into the estuary, collects 96% of runoff in the 4,500 km2 Tijuana River watershed. Stream flow in the Tijuana...

Biotic response of Tethyan bathyal ostracodes through the Eocene-Oligocene Transition from the Massignano Composite Stratotype Section (east central Italy) - The Eocene-Oligocene Transition (EOT) is marked by a double-stepped ~1.3‰ positive excursion in d18O over an ~300 kyr interval (i.e., Oi-1; Miller et al., 1991; Zachos et al., 1996; Coxall et al., 2005) and a deepening of the calcium compensation depth (CCD) interpreted to represent marked Antarctic glaciation and global...

Tidal Bore on the Severn River - Tides progress up the Severn River in SW England as a tidal bore moving faster than 6 m/s. During spring tides, the leading edge of the bore can be up to 2 m high, taking more than an hour to travel from the lower portion of the river to past Gloucester. This is sufficient to attract surfers from around the world. The North Atlantic amphidromic system interacts with the broad continental shelf around the U.K. to produce a complicated field of large tidal...
