The Challenging Depths of Titan's Seas

Abstract

Abstract New analyses of Cassini radar altimeter data (Poggiali et al., 2020, https://doi.org/10.1029/2020JE006558) measure the 85 m depth and “brackish” (moderately ethane‐poor) composition of Moray Sinus, an estuary at the northern margin of Titan's largest sea, Kraken Mare. No bottom echo was detected on Kraken itself, suggesting it is either very deep, ethane‐rich, or both.
