Let's build an Airport – How to estimate large scale projects☕ 🥧 🚲 Martin Gude
Estimating large scale projects always seems like a pain in the ass. In the end it's just a pretty straightforward three step process: gather the information, define the tasks and estimate those tasks. And you're done.
This document provides a summary of Jørn A. Jernsletten's career goals, personal background, education and training, and work experience.

This document compares two transient electromagnetic (TEM) surveys conducted in Mars analog environments to detect groundwater. A TEM survey in Arizona detected groundwater at 120m depth, consistent with test wells. A TEM survey at Peña de Hierro, Spain detected groundwater at 90m and 15m depths at two sites, consistent with initial drilling results. The surveys used different loop configurations and frequencies to investigate depths from 100-550m. The studies demonstrate TEM is effective for deep groundwater detection in Mars analog sites.
This study analyzes north-south components of slope angles in Mars' global topography to determine if equatorward facing slopes in mid to high latitudes are steeper than poleward facing slopes, based on the hypothesis of sublimation exhuming an ice-rich crust. Past studies showed individual troughs in the polar layered deposits have steeper equatorward slopes. The current study finds empirical evidence that equatorward slopes are 0.1-0.3 degrees steeper than poleward slopes on a global scale, lending topographical support for an ice-rich shallow crust in mid to high latitudes on Mars. The study uses MOLA elevation data to calculate slope angles, aspects, north-south slope
This document summarizes two field studies that used time domain electromagnetics (TEM) to investigate subsurface water in Mars analog environments. A TEM survey in Arizona was able to image around 500 meters depth and locate groundwater around 120 meters deep, consistent with well data. A separate fast-turnoff TEM survey in Spain imaged around 200 meters depth with a conductive layer at 90 meters interpreted as the water table. Both studies demonstrate TEM is suitable for probing deep groundwater relevant to Mars.

This document summarizes a study that analyzed topographic data from Coprates Chasma on Mars to test the hypothesis that variations in slope angle along the trough walls are consistent with differences in the past distribution of ground ice. The study measured slope angles, temperatures, and wall geometry from 247 topographic profiles across the trough. The results found no evidence that differences in ground ice distribution caused the variations in slope angle, implying ground ice has been absent from the walls since the terrain formed. This precludes theories that the terrain formed through dry mass wasting above an ice-rich layer or that ice played a role in landslides.
This document discusses using transient electromagnetics (TEM) and ground penetrating radar (GPR) to sound subsurface water on Mars. It presents field data from Arizona, Spain, and Egypt to compare the two methods. TEM can investigate deeper depths but with lower resolution, mapping large aquifers. GPR provides higher resolution at shallower depths useful for near-surface layers and clays. Both methods could potentially detect subsurface water on Mars, with GPR best for shallow targets and TEM for deeper structures like aquifers. The document concludes by comparing key parameters of GPR and TEM and their appropriate applications.
This document summarizes evidence for the past and present distribution of water on Mars in its three phases - solid, liquid, and vapor. It discusses the theoretical and observational evidence for each phase, including calculations of the depth of the Martian cryosphere based on thermal modeling, constitutive relations for ice deformation, comparisons of Martian and terrestrial rock glaciers, and analysis of slope asymmetry in polar layered deposits indicating differential sublimation erosion of ice-rich material. Spatial and temporal variations in atmospheric water vapor from early telescopic observations through recent TES data are also summarized.
The document discusses possible temperature-related differences in slope and surface roughness between the north and south walls of Coprates Chasma on Mars. It presents background information on the geology and stratigraphy of the region. The author then discusses how temperature affects the rheology and creep behavior of ice-rich geologic materials over geological timescales. Topographic data from MOLA is analyzed to measure any measurable differences in slope angles and surface roughness between the north and south facing walls that could result from expected temperature differences.
