Geomorphological processes on terrestrial planetary surfaces [PDF]

open access: yes, 1980
This review deals with features and processes on planetary surfaces, first by examining the impact of photographic explorations of Moon, Mars, and Mercury on studies of surface processes on our own planet, and second by treating matters related to ...

Kilauea Iki lava lake experiment plans [PDF]

open access: yes, 1981
Twelve experimental studies are proposed to complete field laboratory work at Kilauea Iki lava lake. Of these twelve experiments, eleven do not require the presence of melt. Some studies are designed to use proven techniques in order to expand our existing knowledge, while others are designed to test new concepts.

Arctic ecosystem restoration with native tundra bryophytes

open access: yesArctic, Antarctic, and Alpine Research, 2023
Bryophytes are ecologically essential to northern ecosystem restoration after disturbance. In this study, native bryophytes were used to revegetate two Arctic restoration sites. Different propagation types (small, medium, large fragments) and substrates (

Fossil trees, tree moulds and tree casts in the Palaeocene Mull Lava Field, NW Scotland: context, formation and implications for lava emplacement [PDF]

open access: yes, 2016
Megafossils and macrofossils of terrestrial plants (trees, leaves, fruiting bodies, etc.) are found in sedimentary and pyroclastic units interbedded with lavas in many ancient lava fields worldwide, attesting to subaerial environments of eruption and the

Lunar “Volcanoes” and Lava Lakes [PDF]

open access: yesNature, 1893
I HAVE waited some time to see what replies might be made to Mr. J. B. Hannay's suggestion, that lunar walled plains may have been due to tides in the molten nucleus during crust formation (NATURE, vol. xlvii. p. 7).

Application of Phytoplankton Taxonomic α-Diversity Indices to Assess Trophic States in Barrier Lake: A Case of Jingpo Lake

open access: yesDiversity, 2022
Phytoplankton taxonomic α-diversity indices are useful tools to characterize the trophic states in freshwater ecosystems. However, the application of these indices to assess trophic states in large barrier lakes is rare, especially in China.

A new infrared volcano monitoring using GCOM-C (SHIKISAI) satellite: applications to the Asia-Pacific region

open access: yesEarth, Planets and Space, 2020
The GCOM-C (SHIKISAI) satellite was developed to understand the mechanisms of global climate change. The second-generation global imager (SGLI) onboard GCOM-C is an optical sensor observing wavelengths from 380 nm to 12.0 μm in 19 bands.

The Lava-Lake of Kilauea [PDF]

open access: yesNature, 1902
THE recent destructive eruption in Martinique has revived interest in the question of the causes of volcanic action. Only lately have I become sensible of the peculiar value of some observations of my own as evidence of the primary force which impels the ascent of lava from its interior habitat, as distinguished from the explosive violence caused by ...

Mono Lake or Laschamp geomagnetic event recorded from lava flows in Amsterdam Island (southeastern Indian Ocean)

open access: yes, 2003
We report a survey carried out on basalt flows from Amsterdam Island in order to check the presence of intermediate directions interpreted to belong to a geomagnetic field excursion within the Brunhes epoch, completing this paleomagnetic record with ...

Two Acheuleans, two humankinds. From 1.5 to 0.85 Ma at Melka Kunture (Upper Awash, Ethiopian highlands) [PDF]

open access: yes, 2017
The Acheulean is the longest-lasting human cultural record, spanning approximately 1.5 Ma and three continents. The most comprehensive sequences are found in East Africa, where, in large-scale syntheses, the Lower Pleistocene Acheulean (LPA) has often ...
