Could the Late Permian deep ocean have been anoxic
Models ofocean circulation and biogeochemical cy les are used to speculate bout possible m chanisms of deep-sea anoxia across the Pertoo-Triassic boundary. Two modes of likely Late Permian ocean thermohaline circulation are identified: a vigorous "therm',d mode" driven by cooling in southern polar latitudes and aweaker "haline mode" driven by evaporation fromthe subtropics. We find that the the...
متن کاملReply to Comment by Roberta M. Hotinski, Lee R. Kump, and Karen L. Bice on ‘‘Could the Late Permian deep ocean have been anoxic?’’
[1] Two recent studies [Hotinski et al., 2001; Zhang et al., 2001] have modeled and discussed Late Permian ocean circulation and oxygenation. These studies have reached significantly different conclusions. Zhang et al. [2001] find that a ‘‘thermal mode’’ ocean circulation driven by cooling in polar latitudes is unlikely to support deep-sea anoxia, but a ‘‘haline mode’’ ocean circulation, a shal...
متن کاملCould meltwater pulses have been sneaked unnoticed into the deep ocean during the last glacial?
[1] The lack of climatic imprint left by the Meltwater Pulse-1A (’14.5 ka BP), equivalent to a sea-level rise of 14 to 20 meters, is puzzling. Recent studies suggest the event might have occurred as a hyperpycnal flow in the Gulf of Mexico, preventing its detection in oceanic records throughout the North Atlantic. We present a suite of simulations with the LOVECLIM climate model, which mimic th...
متن کاملThe 'What Could Have Been' Photo
The goal of the project is to create new scenarios in a supplied photo by replacing some of its elements with elements from other photos. This could be used to repair imperfectly taken photos (photo with shadow due to camera lens that was partially covered by finger), to remove elements that spoil the imagery of a picture (a garbage can in the middle of a rose garden), or to create an image wit...
متن کاملCould the Recent Zika Epidemic Have Been Predicted?
Given knowledge at the time, the recent 2015-2016 zika virus (ZIKV) epidemic probably could not have been predicted. Without the prior knowledge of ZIKV being already present in South America, and given the lack of understanding of key epidemiologic processes and long-term records of ZIKV cases in the continent, the best related prediction could be carried out for the potential risk of a generi...
