Then you'll need to reinstall an OS and your applications, after which the Powerbook should be fine again - minus your data. If the drive is dead, it will cost you about $60-100 to buy a new hard drive and take you about 20 minutes to install it yourself. A data recovery service may be able to salvage some or all of the data from a stone-dead drive for you, but at a cost similar to or greater than what you paid for your new MacBook. This is why people back their data up, and why you may start to do so yourself in the future. If the drive has really died, there's nothing you can do yourself to recover your data. If that's the only problem, you can fix it with the press of a finger, and probably have your Powerbook back up and running in the five minutes it will take you to put the bottom cover back on and press the startup button. It would be well worth checking that cable's connection. 2 Department of Biology, University of Regina. When you turn on the G4, if there is no soft (or louder) whirr of the hard drive spinning, then either the drive is stone dead, or it isn't getting any power because its cable has come loose from the logic board. 1 The Living Data Project, Canadian Institute of Ecology and Evolution, Vancouver, British. If DR doesn't see the drive, it can't salvage anything, because the drive is not spinning or its controller is defunct. If so, select the drive and follow DR's on-screen user instructions. Start the Powerbook up with your Data Rescue CD and see whether DR can "see" the hard drive then. More generally, these data and data from other historical sources are used to improve the models and reanalysis systems used in climate and weather research.Hi, Nick. the International and Comprehensive Ocean-Atmosphere Data Set, ICOADS, ), which will be used to generate new estimates of the industrial and pre-industrial era baseline climate. The data generated through the GloSAT project will help fill many crucial gaps in the large climate datasets (e.g. They contain six, 4-hourly, meteorological observations per day.įigure 3: Sample logbook image used in the new citizen-science zooniverse project Logbooks (figure 3) archived at the UK Hydrographic Office (UKHO) are best suited to produce data in the early-industrial time period with global coverage. It aims to fill-in gaps in space and time in global climate datasets by strategically prioritizing logbooks, focusing on those containing at least air temperature (AT) or sea-surface temperature (SST) observations. New citizen-science project - Weather Rescue Rescue at SeaĪ new citizen-science project, Weather Rescue at Sea, has been created on zooniverse. The transcribed data generated through the zooniverse platform is processed and quality controlled, producing invaluable WWII daily weather data.įigure 2: Ship tracks of the US Navy Ship Salt Lake City, 1941ģ. These vessels traversed mainly the Pacific and Atlantic Oceans (figure 2). These logbooks contain 4-hourly meteorological observations, with parameters including Sea-level pressure (SLP), air temperature (AT) and sea-surface temperature (SST). The Old Weather - WWII citizen science zooniverse project, led by NOAA, involves the transcription of US cruiser and destroyer logbooks (deployed during WWII) by volunteers. As a part of the GloSAT data-rescue effort, the data in these spreadsheets is standardised, quality checked, and formatted into a widely used research format (IMMA).įigure 1: Ship tracks of HOPE, travelling westward was part of the first Russian Circumnavigation Expedition (1803-1806), with sea-level pressure (SLP) measured through the journey (inset) However, these observations are recorded in various formats, frequencies and units, rendering them unusable for systematic research. A large number of logbooks have been transcribed and are stored in individual spreadsheets (figure 1). National and Thematic affiliates of The Atmospheric Circulation Reconstructions over the Earth (ACRE) project conduct data-rescue by engaging individual researchers. Standardizing data transcribed by the ACRE project There are three strands to the data-rescue activities: 1. The focus is on measurements taken on board ships travelling through the Atlantic, Indian and Pacific ocean basins. Data Rescue II is also completely safe to use since it does not attempt any risky repairs to the drive while its scanning. Data Rescue II works when other tools fail. GloSAT will use a 'citizen science' approach to recover observations and make them usable. Data Rescue II is the best data recovery software on the market for recovering files from a problem hard drive or files that have been previously deleted. Millions of weather observations taken over a century ago are not available to climate scientists as they only exist as hand-written measurements in various logbooks stored in archives around the world.
