This study analyzed calcium carbonate (%CaCO3) and oxygen isotope (δ18O) data from sediment core samples at Ocean Drilling Program Site 1090 in the Atlantic sector of the Southern Ocean to better understand fluctuations in the Calcite Compensation Depth (CCD) and link them to climate changes between 36-40 million years ago during the Eocene period. %CaCO3 values showed wide variation and corresponded to bulk sediment δ18O values downcore. High %CaCO3 and δ18O values indicate a shallow CCD and warmer climate, while low values suggest a deeper CCD and cooler climate including possible Antarctic glaciation. The results support the hypothesis that CCD changes reflected global cooling events and

1. The document analyzes changes in land use and land cover (LULC) in coastal counties in South Carolina between 1996 and 2006 using remote sensing data.
2. It finds increases in surface water cover, scrubland, and development likely due to rising sea levels and population growth, while forests and woody wetlands decreased.
3. More detailed long-term LULC studies are recommended to better understand trends and their environmental and economic impacts on the coastal region.
This document summarizes the findings of a group of researchers who met to discuss common misunderstandings about the causes of land-use and land-cover change. It aims to move beyond simplistic explanations and instead present a more nuanced understanding based on case study evidence. The researchers concluded that population growth and poverty alone do not drive tropical deforestation as often believed. Rather, deforestation is influenced by changing economic opportunities which are mediated by institutional and policy factors. Rangelands are also not simply natural systems but are maintained through interactions between human and environmental factors. Land use changes are complex processes influenced by local conditions as well as national and global forces.
Landslide Investigation of Ikwette, Obudu Local Government Area of Cross Rive...iosrjce
This study investigates the causes of a slope failure at Ikwette, Obudu local Government Area of
Cross River State, Nigeria in 2013. It also involves a slope stability analysis of the failed slope, which was OB1.
To understand instability in the study area, a combination of field, geotechnical and statistical analysis were
undertaken. Some obtained parameters were then applied in a slope/W Geostudio 2012 software program which
uses the conventional limit equilibrium methods to simulate the dominant factors inducing instability. Results of
the geotechnical investigations of the samples taken from Ikwette, showed an average maximum dry density
value of 1.63kg/m3
, which was a low to moderate value and average optimum moisture content value of 18%.
Analysis from the particle size distribution, showed that the particle sizes where silty sand, with a Coefficient of
uniformity (Cu) value of 1.8 and Coefficient of curvature (Cc) value of 0.968, indicating that the soil is
uniformly or poorly graded. Triaxial compression test showed an angle of internal friction and cohesion values
averaging around 12.65° and 43kPa respectively, which indicates that the shear strength of the soil was
reduced, due to the activities of high precipitation intensity which increased to a monthly value of 375.3mm
before the landslide event. Also, the factor of safety value for the slope in OB1, where the landslide occurred
was 1.114, which is close to the value for an incipient failure. Hence the results of the aforementioned methods
and simulation shown can be used in predicting areas of possible landslides, as well as the causes of such soil
deformations, and as such, safety measures could be taken against the reoccurrence of landslides in such areas.

Geoelectrical and Hydrochemical Assessment of Groundwater for Potability in E...Premier Publishers
Geoelectrical and hydrochemical investigations were carried in order to determine the potentials and quality of groundwater in Ebonyi North, Southeastern Nigeria. These methods were also selected to determine their economy and accuracy compared to seismic method. Fifteen (15) vertical electric sounding (VES) survey were conducted using the Schlumberger configuration in order to evaluate the character of the aquifers in the studied locations while twelve (12) groundwater samples were collected from boreholes for hydrochemical analysis. Geoelectric sections derived from modelling of the VES data with the interpex IX1D software reveal 3 to 5 subsurface layers. The lithologic succession comprises of topsoil, lateritic clay, partially weathered, weathered and fractured Asu River shale. The weathered and fractured layers constituted the productive water bearing or aquiferous zones of good groundwater potentials. Hydrochemical analysis of groundwater samples reveals that the pH range from 7.8 to 8.8, electrical conductivity from 10.0 to 1754.00 μS/cm, total dissolved solid from 10.0 to 786.0 mg/l and total hardness from 14.0 to 271.0 mg/l. The analytical results present the concentration of the ions in the following order: Mg > Ca > Na > K and Cl > SO4 >HCO3> NO3 > CO3. Piper trilinear diagram reveals only one water type, with Ca and Cl as the major dominant ions. The major ions concentrations are within recommended standard for drinking, hence the groundwater from the area is suitable for drinking and domestic purposes.
Geophysics is a multidisciplinary field that uses quantitative physical methods to study the Earth and surrounding space environment.

It involves the study of potential fields, diffusive fields, and wave propagation through various methods including seismic, gravity, magnetic, electrical, and electromagnetic techniques.
This document discusses reservoir geophysics and geology. It begins with an introduction to geophysics, noting that most rocks are opaque so geophysics uses physics to obtain "geophysical images" of the subsurface based on properties like density, magnetism, conductivity, and velocity. It discusses using natural fields like gravity and magnetics to measure subsurface variations at a regional scale. Later sections discuss seismic reflection methods, potential field applications in mapping geology, and benefits of 3D seismic over 2D in providing better geological models. The document provides an overview of key concepts in reservoir geophysics and geology.

This document summarizes findings from imaging and thermal analysis of asteroid Bennu by NASA's OSIRIS-REx spacecraft. It finds that Bennu's surface is globally rough, dense with boulders over 1 meter in size, and has a low albedo of 4.4%. Thermal data indicates a moderate global thermal inertia of 350 J m-2 K-1 s-1/2, suggesting surface particle sizes of 0.5-5 cm by simple models, however images show the surface is dominated by boulders over 1 meter. Over 80% of the surface was analyzed, finding a power law distribution of boulder sizes with an index of -2.9 for boulders 8 meters
This document discusses planetary and tidal wave oscillations observed in ionospheric sporadic E layers over Tehran, Iran. Wavelet analysis was used to examine time series data of critical frequency (foEs) and virtual height (h'Es) of sporadic E layers from July 2006 to June 2007. The results show:
1) Diurnal (24-hour) and semidiurnal (12-hour) oscillations were present in all seasons for both foEs and h'Es. Terdiurnal (8-hour) variations were also observed.
2) Planetary wave oscillations of around 2, 4, 6, and 10 days were observed, with maximum activity during equinox seasons.

Geopathic Stress : A Threat to Built EnvironmentPramey Zode
Geopathic Stress is the energy from the earth surface which is the biggest threat to the built environment. Energy emitted by the earth surface which has ability to change the normal functioning of human beings is termed as Geopathic stress. World health Organisation in 1992 has identified that a building can make a person sick. The presence of ground water vein is closely associated with generation of such a stress and in turn it affects the built environment. Built Environment constitutes houses, roads, footpaths, shops etc. Geopathic Stress affects almost each and every part of the built environment. This energy penetrates metals, concrete and other substance which have high degree of impermeability. Although moving away from a stress zone is easier in residential built environment but it is difficult for the road environment where the accidents occurs because of such stresses. In the road environment, concrete may get deteriorated and cracks may get developed because of such stresses. The chances of lightening are more on such geopathically stressed zones. Also if geopathic stress is present on road environment, it may lead to increased reaction time of drivers in turn responsible for occurrence of accidents. If people sleep on such stress zones, they are susceptible to various diseases like cancer. Hence ‘GEOPATHIC STRESS’ is the threat to the built environment.
Modification and Climate Change Analysis of surrounding Environment using Rem...iosrjce
This document discusses the application of remote sensing (RS) and geographic information systems (GIS) in analyzing climate change and the surrounding environment. It begins by defining key terms related to climate, climate change, and RS and GIS. It then highlights several areas where RS and GIS have been applied, including glacier monitoring, vegetation change monitoring, and carbon trace/accounting. Studies are discussed that use RS and GIS to monitor glacier retreat, snow depth, land cover change, and above-ground carbon stocks. The document concludes that RS and GIS play a crucial role in understanding and managing climate change by providing important spatial data and enabling the monitoring of environmental changes over time.
This document discusses opportunities for international collaboration on understanding climate change. It outlines key issues including the need for open data exchange, the many potential partners across nations and agencies, balancing scope and continuity of observations, deciding between collaborative missions or programs, and coordinating roles between entities. The goal is to efficiently and effectively address the large challenge of climate change through collaborative Earth system science.

1) Apatite samples from the Grand Canyon basement were analyzed using 4He/3He thermochronometry to constrain the near-surface cooling history associated with canyon incision.
2) Data from eastern Grand Canyon apatites indicate substantial canyon incision by ~70 million years ago, earlier than conventional models suggesting incision began 5-6 million years ago.
3) Similar data from western Grand Canyon provide evidence that it was excavated to within a few hundred meters of its modern depth by ~70 million years ago, challenging the view that the entire canyon was carved only in the last 5-6 million years.
Adélie Penguin Population Trends in Cape BirdJessica Carde
1) The document analyzes historic aerial photographs from 1956-2009 of the Cape Bird Adélie penguin colony in Antarctica to study population trends over time in response to climate change.
2) Using GIS software, the author counts penguins in 1983 photos and outlines guano-stained areas in older photos to estimate colony sizes. All three rookeries at Cape Bird increased in size between 1956-2009, with the largest growth in the Middle Rookery.
3) Climate change, competitive release from declining whale populations, and decreased fishing of prey species likely all contributed to the increasing Cape Bird penguin population observed over the past 60 years.

This paper titled Seismic Refraction Survey for Groundwater Potentials of Southern Paiko Area.
Niger State, Nigeria, employs the service of seismic refraction survey method. A twelve-channel seistronix was
used for the data collection. The profiles were marked at 100 m intervals, while the profiles lines traversed
1000 m (1km). A Total of 44 spreads were shot. Data were collected, Time – distance (T-S) graphs were plotted
using matrix laboratory software, velocities of the underlying layers obtained and depths to the refractor layer
computed and geologic cross sections were obtained. The results obtained gave an overview of the lateral
variation in the lithological changes of the subsurface earth materials in the surveyed area. The basement
surface varied in depth, from 10.16 m to a maximum of 14.80 m. weathered layer velocities ranging from 809
m/s to 3612 m/s and consolidated layer velocities varying between 2858 m/s to 9696 m/s. Four shot points were
delineated as aquifer potentials of the area having depth to refractor varying between 13.70 m and 14.80 m with
overburden velocities ranging from 1940 m/s to 3462 m/s. The rock materials identified in the surveyed area are
chiefly sand, saturated clay, gravel, gneiss, igneous rock and granite.

1) Apatite samples from the Grand Canyon basement were analyzed using 4He/3He thermochronometry to constrain the near-surface cooling history associated with canyon incision.
2) Data from eastern Grand Canyon apatites indicate substantial canyon incision by ~70 million years ago, earlier than conventional models suggesting incision began 5-6 million years ago.
3) Similar data from western Grand Canyon provide evidence that it was excavated to within a few hundred meters of its modern depth by ~70 million years ago, challenging the view that the entire canyon was carved only in the last 5-6 million years.
Adélie Penguin Population Trends in Cape BirdJessica Carde
1) The document analyzes historic aerial photographs from 1956-2009 of the Cape Bird Adélie penguin colony in Antarctica to study population trends over time in response to climate change.
2) Using GIS software, the author counts penguins in 1983 photos and outlines guano-stained areas in older photos to estimate colony sizes. All three rookeries at Cape Bird increased in size between 1956-2009, with the largest growth in the Middle Rookery.
3) Climate change, competitive release from declining whale populations, and decreased fishing of prey species likely all contributed to the increasing Cape Bird penguin population observed over the past 60 years.
Seismic Refraction Survey for Groundwater Potentials of Northern Paiko Area. ...iosrjce
This paper titled Seismic Refraction Survey for Groundwater Potentials of Southern Paiko Area.
Niger State, Nigeria, employs the service of seismic refraction survey method. A twelve-channel seistronix was
used for the data collection. The profiles were marked at 100 m intervals, while the profiles lines traversed
1000 m (1km). A Total of 44 spreads were shot. Data were collected, Time – distance (T-S) graphs were plotted
using matrix laboratory software, velocities of the underlying layers obtained and depths to the refractor layer
computed and geologic cross sections were obtained. The results obtained gave an overview of the lateral
variation in the lithological changes of the subsurface earth materials in the surveyed area. The basement
surface varied in depth, from 10.16 m to a maximum of 14.80 m. weathered layer velocities ranging from 809
m/s to 3612 m/s and consolidated layer velocities varying between 2858 m/s to 9696 m/s. Four shot points were
delineated as aquifer potentials of the area having depth to refractor varying between 13.70 m and 14.80 m with
overburden velocities ranging from 1940 m/s to 3462 m/s. The rock materials identified in the surveyed area are
chiefly sand, saturated clay, gravel, gneiss, igneous rock and granite.

Geo Environmental Investigation of Abuad Dumpsite, Southwestern NigeriaIJERA Editor
Geoenvironmental study of ABUAD female dumpsite was conducted to investigate the suitability of its location
and potential impact on groundwater in the environment. Profiling and Vertical electrical sounding methods
were employed using Dipole - Dipole and Schlumberger configuration respectively. Five points were sounded
and one profile was occupied. Three heterogeneous subsurface lithologic units were established namely; lateritic
topsoil, clayey-sand, and, fresh basement. The curve types are simple H and HA. The topsoil and clayey-sand
materials are characterized with relatively low resistivity values while the fresh basement materials are
characterized with high resistivity values. The average resistivity and thickness values for the topsoil are
280.0Ωm and.2.3m respectively. Clayey-sand was encountered in all the locations with average resistivity and
thickness values of 32.0Ωm and 7.3m respectively. Basement is relatively shallow in the study area, it was
encountered in all the locations with an average resistivity and depth values to the top of basement of 674Ωm,
and 9.6m respectively. Overburden materials are relatively thin within the area with an average resistivity and
thickness values of 156Ωm, and 9.6m respectively. The overburden materials constituting the aquiferous units
within the study area are porous, vulnerable, and good paths for leachate migration. The relatively low
resistivity values within the clayey-sand layers (14 - 61Ωm) are suggestive of leachate intrusion, while relatively
high resistivity values of the impervious basement are due to their crystalline nature. The proximity of the
dumpsite to both the cafeteria and residential halls is a cause for concern.
