A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes

During one week (28 March-4 April 1982), three powerful explosive eruptions (VEI 5) of El Chichón Volcano caused the worst volcanic disaster in Mexico’s recorded history. Pyroclastic flows and surges obliterated nine villages, killing about 2,000 people,

Simulation and observations of stratospheric aerosols from the 2009 Sarychev volcanic eruption [PDF]
We used a general circulation model of Earth’s climate to conduct simulations of the 12-16 June 2009 eruption of Sarychev volcano (48.1°N, 153.2°E).

Abstract The occurrence of sea surface temperature (SST) extremes may provoke profound impacts on ocean health. In the last decade, much effort has been dedicated to understanding and systematically describing marine heatwaves (MHWs) and cold spells (MCSs), defined as prolonged periods of anomalously warm or cold SSTs at a given location, respectively.

Large explosive volcanic eruptions are capable of injecting considerable amounts of particles and sulfur gases above the tropopause, causing large increases in stratospheric aerosols. Five major volcanic eruptions after 1960 (i.e., Agung, St.

Eruption Column Modeling of Explosive Volcanism on Venus
Abstract Volcanism on Venus has never been directly observed, but several measurements indicate present‐day activity. Volcanism could potentially play a role in climatic processes on Venus, especially in the sulfur cycle like on Earth. Observation of volcanic activity is the primary objective of future Venus spacecraft. However, there are many unknowns

Enormous increase of volcanic clouds in the stratosphere over Fukuoka after April 1982
Mediante el sistema lidar Yag se observaron sobre Fukuoka (33°N) aumentos muy grandes de los aerosoles estratosféricos causados por la erupción del volcán mexicano El Chichón, a principios de abril de 1982.

Atmospheric temperature responses to solar irradiance and geomagnetic activity [PDF]
The relative effects of solar irradiance and geomagnetic activity on the atmospheric temperature anomalies (Ta) are examined from the monthly to interdecadal timescales. Geomagnetic Ap (Ap) signals are found primarily in the stratosphere, while the solar

The Impact of Natural External Forcing on Ocean Heat Uptake Efficiency Since the 1980s
Abstract We investigate the temporal evolution of ocean heat uptake efficiency (OHUE) using observations and large ensemble model simulations. OHUE, defined as the ratio of ocean heat uptake rate to changes in global mean surface temperature anomalies, has exhibited significant variability over recent decades. We found a relatively low OHUE in the late

Geometry of the Benioff zone in the Tehuantepec area in Southern México
Mediante el uso de. datos de las estaciones VHO, COM y una red sísmica local que operó durante 1979 en Chiapas, en el sureste de México, la geometría de la zona de Benioff mas allá de los 60 km de profundidad ha sido bien delimitada en el área de ...
