There were more than 30,000 merchant ships greater than 1000 gross tonnage at sea in 2005. The World Meteorological Organization has a Voluntary Observing Ships Scheme that equips ships with weather instruments in order to provide observations for weather models and forecasters. In addition to observing the weather, the location of the ships is also recorded through GPS. From October 2004 through October of 2005 1,189,127 mobile ship data points were collected from 3,374 commercial and research vessels, which is about 11% of all ships at sea in 2005. By connecting the data points for each vessel, shipping routes over the course of one year were plotted. The National Center for Ecological Analysis and Synthesis compiled this data to include in their Global Map of Human Impacts to Marine Ecosystems.
As seen in this dataset, there are several very popular shipping routes around the world. The density of ship tracks in any location ranges from 0 to 1,158 on this map, showing relative density (in color) against a black background with scale of 1 km. Some of the most populated shipping routes cross through the Panama Canal, the Suez Canal, the Strait of Malacca , and the Strait of Gibraltar. Because only 11% of ships are represented in this dataset, the density of ship traffic is not fully portrayed and is biased to the types of ships that volunteered for the program. The map creators suggest that the high traffic locations may be strongly underestimated. In spite of this, there are enough data points to highlight some of the busiest shipping routes. There is also a version of this dataset with the major canals and straits labeled.
C1 Patterns. Children recognize that patterns in the natural and human designed world can be observed, used to describe phenomena, and used as evidence
C1 Patterns. Students identify similarities and differences in order to sort and classify natural objects and designed products. They identify patterns related to time, including simple rates of change and cycles, and to use these patterns to make predictions.
C1 Patterns. Students recognize that macroscopic patterns are related to the nature of microscopic and atomic-level structure. They identify patterns in rates of change and other numerical relationships that provide information about natural and human designed systems. They use patterns to identify cause and effect relationships, and use graphs and charts to identify patterns in data.
C1 Patterns. Students observe patterns in systems at different scales and cite patterns as empirical evidence for causality in supporting their explanations of phenomena. They recognize classifications or explanations used at one scale may not be useful or need revision using a different scale; thus requiring improved investigations and experiments. They use mathematical representations to identify certain patterns and analyze patterns of performance in order to re-engineer and improve a designed system.
ESS3.A Natural Resources. Living things need water, air, and resources from the land, and they live in places that have the things they need. Humans use natural resources for everything they do.
ESS3.C Human Impact on Earth systems. Things people do can affect the environment but they can make choices to reduce their impacts.
PS4.C Information Technologies and Instrumentation. People use devices to send and receive information.
ESS3.A Natural Resources. Energy and fuels humans use are derived from natural sources and their use affects the environment. Some resources are renewable over time, others are not.
ESS3.C Human Impact on Earth systems. Societal activities have had major effects on the land, ocean, atmosphere, and even outer space. Societal activities can also help protect Earth’s resources and environments.
PS4.C Information Technologies and Instrumentation. Patterns can encode, send, receive and decode information.
ESS3.A Natural Resources. Humans depend on Earth’s land, ocean, atmosphere, and biosphere for different resources, many of which are limited or not renewable. Resources are distributed unevenly around the planet as a result of past geologic processes
ESS3.C Human Impact on Earth systems. Human activities have altered the biosphere, sometimes damaging it, although changes to environments can have different impacts for different living things. Activities and technologies can be engineered to reduce people’s impacts on Earth.
PS4.C Information Technologies and Instrumentation. Waves can be used to transmit digital information. Digitized information is comprised of a pattern of 1s and 0s.
ESS3.A Natural Resources. Resource availability has guided the development of human society and use of natural resources has associated costs, risks, and
ESS3.C Human Impact on Earth systems. Sustainability of human societies and the biodiversity that supports them requires responsible management of natural resources, including the development of technologies that produce less pollution and waste and that preclude ecosystem degradation.
PS4.A Wave Properties. The wavelength and frequency of a wave are related to one another by the speed of the wave, which depends on the type of wave and the medium through which it is passing. Waves can be used to transmit information and energy.
PS4.B Electromagnetic Radiation. Both an electromagnetic wave model and a photon model explain features of electromagnetic radiation broadly and describe common applications of electromagnetic radiation.
PS4.C Information Technologies and Instrumentation. Large amounts of information can be stored and shipped around as a result of being digitized.
