The hydroclimatology of Gorgona Island: seasonal and ENSO-related Patternsa

Actualidades Biológicas, 2012
Most small watersheds in the Tropical Eastern Pacific remain ungauged, and discharge analyses using gauge and simulated data have been published only for a few large rivers. I analyzed a 20-yr record of rainfall and stream discharge from Gorgona Island, a natural national park located 30 km offshore in the Pacific Ocean of Colombia to explore intra ...

Macroinvertebrate assemblages in Gorgona Island streams: spatial patterns during two contrasting hydrologic periods

Actualidades Biológicas, 2012
Studies comparing various streams are scarce in tropical insular systems and inexistent in Colombia. In order to understand the spatial patterns of macroinvertebrates in tropical insular streams, and the environmental drivers of such patterns, we tested for patterns among streams but using a nested sampling design from streams to microhabitats in ...

Shell-size variation of Notoacmea biradiata (Archaeogastropoda: Acmaeidae) as a response to gastropod density and height in shore in the Colombian Pacific coast

Ciencias Marinas, 2002
Notoacmea biradiata (Reeve, 1855) is an abundant intertidal limpet on the rocky shore of the Colombian Pacific coast. This paper reports a field factorial experiment on shell-size variation of N.

Nickel and helium evidence for melt above the core–mantle boundary [PDF]

, 2013
High ^(3)He/^(4)He ratios in some basalts have generally been interpreted as originating in an incompletely degassed lower-mantle source. This helium source may have been isolated at the core–mantle boundary region since Earth’s accretion. Alternatively,

Breeding ecology and conservation of Brown booby in Gorgona Island, eastern tropical Pacific Ocean [PDF]

, 2011
Breeding ecology and reproductive traits of Brown Booby _Sula leucogaster_ etesiaca in Gorgona Natural National Park, Colombia, were studied. Adults morphometrics, eggs dimensions, chicks growth and nesting site characteristics, were examined at three ...

A Possible Tsunamigenic Near‐Trench Strike‐Slip Fault, Offshore North Ecuador–South Colombia

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Seismic reflection and bathymetry collected along the Ecuador–Colombia obliquely convergent margin allow the first characterization of the NNE‐trending, near‐trench strike‐slip Ancon Fault in the possible source region of the 1906‐Mw8.6–8.8 and 1979‐Mw8.2 earthquakes, which produced devastating tsunamis.

First record of humpback whale songs in Southern Chile: Analysis of seasonal and diel variation [PDF]

, 2018
Male humpback whales (Megaptera novaeangliae) produce complex, patterned songs that are traditionally recorded on their breeding grounds. In this work, we report results from the first continuous acoustic monitoring of a humpback whale feeding ground off

Role of Magma Ocean Differentiation in the Formation and Long‐Term Preservation of Distinct Geochemical Domains Within the Deep Mantle

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract We modeled the evolution of the terrestrial Magma Ocean using the short‐lived 182Hf‐182W isotope system (t1/2 = 8.9 Myr) in a multi‐reservoir early Earth. We start with a chondritic Earth at T0 = 4.567 Ga. Core segregates and attains its present‐day mass, W elemental and isotopic (182W/184W) composition by the end of core formation (TCF).
