Led by their matriarch, T49A Nan, the T49As are one of the most beloved Bigg's killer whale matrilines in the Salish Sea. Until just a few weeks ago, the four-year-old T49A6 Charlie II was the youngest brother in the family, capturing the hearts of orca lovers everywhere. (1/3)

Silicate weathering in the semi-arid Southern Pyrenees during the PETM: lithium isotope evidence Abstract. The Palaeocene-Eocene Thermal Maximum (PETM), a hyperthermal event ∼ 56 Ma ago, allows the Earth system response to abrupt climate change to be explored. Recent investigations link the PETM ...

An Early Miocene ape from the biogeographic crossroads of African and Eurasian Hominoidea The Early Miocene fossil record documenting hominoid evolution has long been restricted primarily to sites in East Africa, whereas contemporaneous North African sites have only yielded remains of cerc...

This major fossil discovery is also an important milestone for home-grown Egyptian paleontology. Congrats to the Mansoura University team, including UMMP's Sanaa El-Sayed! www.science.org/doi/10.1126/...

The DC Metro

The DC Metro

Happy birthday to the Washington Metro, which opened 50 years ago today with service on 4.6 mi of Red Line between Rhode Is. Ave & Farragut N. System now serves 130 mi.

The DC Metro shows that, with good planning & enough investment, the public sector can succeed & build something extraordinary.

(a) Global marine calcium carbonate (CaCO3) budget. Rates are from Tables 2 and 3 and are discussed in the main text. (b) Alkalinity budget, adapted from Middelburg et al. (2020; see Text S4 in Supporting Information S1 for derivations; updated values for CaCO3 burial are discussed in the main text). Uncertainties for all processes are shown within parentheses as G (∼50% uncertainty), F (∼100% uncertainty), or P (more than 100% uncertainty). Reference saturation horizons for high-Mg calcite (HMC), aragonite (Ara), and low-Mg calcite (LMC) are shown in green. Rates shown in red were derived from mass balance calculations and are therefore unconstrained.

"While sedimentary coastal and shelf dissolution has the potential to buffer a substantial amount of the global oceanic CO2 sink on short timescales, off-shelf export transports a significant fraction ... to the long-term CO2 feedback." 🧪🌊
