Atlantis is a sophisticated, data integration tool that allows users to assess the influence of biogeochemical processes and anthropogenic impacts on the ecosystem, as a whole. Atlantis is a full-system, ecosystem model that is being used across the world to assess the impact of environmental processes on the distribution and abundance of marine organisms, and to provide strategic advice to fisheries managers and stakeholders. The Atlantis modelling framework consists of sub-models that incorporate both the biogeochemical components of the marine ecosystem in question and the human realm into model predictions. To represent the fishing industry in this marine ecosystem, we have included 12 commercial and recreational fishing fleets in the model, that together harvest 28 of the 51 model functional groups. Shown is a map of the region, as well as some of the key ecosystem components that are being considered in the Tasman and golden Bay Atlantis model.
A NetCDF file system or Atlantis ecosystem model library e. Note: Remember that if you want a copy of the Atlantis main code you will need to go first to the Atlantis-Page and sign the licence agreement and then send an email to the developers, who will give you access to the code. Compiler Xcode : To install Xcode you might download a dgm file. How has this information helped you? Required libraries Atlantis needs the following libraries to be installed. Once its Gay marriage ireland installing you need to eject it before you delete it from your downloads folder. This model is divided into 9 polygons and has 5 water layers and Atlantis ecosystem model sediment layer. For further information see the Atlantis-Wiki.

This approach is usually spatially explicit, including detailed mapping of overlap Erections plus species, threats, and human users. Back to Previous Page. Feature Story. We can also ask questions about the Atlantis ecosystem model economy. You are commenting using your Google account. Only a small amount of energy Atlantis ecosystem model its way to the top of the food web to species like sharks, tunas, and people. This presents marine and maritime managers with the huge challenge of balancing competing social, conservation, and economic objectives. We can can also use EwE to examine how fisheries and ecosystems interact. Select up to three search categories and corresponding keywords using the fields to the right. For example, we can use the model to evaluate ecosystem effects social, economic, and ecologic of the commercially-important bottomfish fishery and of changes in the Hawaiian monk seal population. Ecosystem-based management is one way that we can start to address these trade-offs. Because Atlantis has a spatially explicit modeling approach, we can explore these types of questions island-wide and by specific areas.

An important part of doing EBM is the judicious use of ecosystem models. Yet the pace of their development and growth of their application warrants formal examination.
One such large, end-to-end ecosystem model is Atlantis. End-to-end models like Atlantis model the full suite of marine ecosystem dynamics, uses, management, and feedbacks thereto. The uniqueness of Atlantis is that it is multisector, modular, has multiple functional forms a user can choose, and is designed particularly to address system-level Management Strategy Evaluation.
Yet what the Atlantis platform needs is further development, testing and evaluation of its myriad modular approaches. Here we propose to hold the first ever Atlantis Summit. There are numerous general ecosystem modelling meetings and workshops that explore some facets germane to Atlantis model development. Other modelling platforms e. Thus, now that the Atlantis platform has similarly matured, what we aim is to have a gathering of the Atlantis modelling community.

Atlantis integrates these dynamics, includes the effects of different user groups, and dynamically tracks the interaction of these factors over time. It also simulates the important processes of assessment, management, and compliance. We adapted the Atlantis framework to study shallow coral reef ecosystems in Guam. Stakeholders identified the main stressors to Guam's reefs, various management strategies, as well as economic and ecological indicators to include in the model for Guam.
We can also ask questions about the local economy. Because Atlantis has a spatially explicit modeling approach, we can explore these types of questions island-wide and by specific areas.
Currently, we are applying the Atlantis software to the insular marine ecosystems of the main Hawaiian Islands. For example, we can use the model to evaluate ecosystem effects social, economic, and ecologic of the commercially-important bottomfish fishery and of changes in the Hawaiian monk seal population.
Additionally, we can evaluate climate impacts and how ocean acidification will alter ecosystem dynamics. Ocean acidification degrades coral reefs, negatively affecting reef fishes that use that ecosystem as their habitat, which in turn will affect the recreational and cultural fishing practices, but also indirectly affects human communities. Since the model includes bi-directional dynamics, we can identify the direct and indirect effects of climate change on human well-being, and on the ecosystem structure and resilience, and evaluate socio-ecological tradeoffs of different management strategies.
Human communities are a key component of ecosystems. To better understand coastal ecosystems on the local level and contribute to ecosystem-based management overall, we work with models that include social and cultural factors alongside ecological and biological information. In West Hawaii, an especially complex and dynamic marine ecosystem, we asked stakeholders to provide input on ecosystem threats and services and then diagrammed the connections in a conceptual ecosystem model.
This model presents a way to apply ecosystem-based management that is both locally-specific and transferable to other locations. Local resource management can better assess the ecosystem pressures that stakeholders specifically identify as influential and important. Critical information can emerge through this process. Increasing our understanding of these intangible benefits to communities will be a critical step toward integrating them into resource management.
Another approach to ecosystem modeling is based on fish size. Therefore, we can construct models based on these size-based relationships. One such model is therMizer. We can use this model to understand how both climate change and fishing might impact the open ocean in the future.
Ecopath with Ecosim EwE models how energy moves through the food web from phytoplankton to apex predators. Species-specific diets are the backbone of this model, so it's important to know which species are predators, and which species they prey on, in order to make the model as accurate as possible. We can use EwE to understand how a change in one species will affect all the other species in the ecosystem. For this reason, some items on this page will be unavailable.

From the Atlantis-Wiki page you can access all the information on the code repository, detailed instructions, and operational examples.
A list of major changes made in new code revisions can be found here and on the Atlantis-Wiki page. The best way to learn about a model, including it's input parameter files and outputs, is through the illustration of an existing operational model. This model is divided into 9 polygons and has 5 water layers and one sediment layer. It has 35 functional groups: 10 are structured by age, 23 are biomass pools, and three are detritus. This model is also forced by outputs from a hydrodynamic model that represent the flows between boxes, also includes forcing of salinity, temperature, fish catches, and arsenic concentration.
Here we provide a brief description of all the input files required to run an Atlantis model. All the input files needed to run the SETas model under Atlantis and output files can be downloaded here. Initial distribution of one functional group. Here we provide a brief description of all the output files from an Atlantis model.
Atlantis generates a number of NetCDF output files that contain spatial information such as the biomass of functional groups in boxes and layers.
To read these outputs you can use your own code or one of the tools listed below. These files can contains a simplified or aggregate version of the information contained in the NetCDF files or and specific output.
There are various tools that help visualise Atlantis output files and many users write their own codes. These tools are listed below. Here we show a few example plots that can be produced with these tools. To process and visualize inputs and output files of an Atlantis model, there exists a number of software.
Below we describe some widely used examples. Atlantistools : Is a data processing and visualization tool for R, which helps to process output from Atlantis models within R. ShinyRAtlantis : An r-based shiny package that can be used to visually assess parameter values and initial conditions of an Atlantis model. This tool was used to produce the figures above. Links to other software used can be accessed via the Atlantis-Wiki.
For detailed model installation and running instructions see chapter 2 in the Atlantis manual Part I. Here we briefly describe the main steps involved. Atlantis is available for multiple operating systems. By using version control tools such as SVN the users are guaranteed to get the correct formatting i. Atlantis is a complex modelling package that is based on a large number of processes, assumptions and equations.
Appropriate and responsible use of such a package therefore requires users to have reasonable computational and basic coding skills. The Atlantis manual provides details on code libraries and routines for the processes included in Atlantis. This means that users can track down specific aspects of the code and make sure they are comfortable with the assumptions of the model.
Developing and calibrating specific model applications is greatly enhanced if users can write their own print statements to understand behaviour of their specific system, e.
This means that the code has to be compiled locally after each print statement. Please note, that checking out, compiling and getting the example model to run on your computer will take about hours. While this may seem long, the development of a new application to your system is likely to take months. If you consider that this timeframe is too long, it is advisable to consider a simpler modelling framework.
Depending on your operating system Atlantis requires the a number of packages and libraries to be installed. This includes software that operates as:. Note: Remember that if you want a copy of the Atlantis main code you will need to go first to the Atlantis-Page and sign the licence agreement and then send an email to the developers, who will give you access to the code.
To get this specific version, please enter this line in your SVN platform. To check the updates and changes in the code since the Atlantis publication, go to the Atlantis Updates page on the wiki. Once you have your compiler, NetCDF reader and source code, it is time to build upload and connect your model files.
After starting the run, Atlantis will start loading input files and will likely give several warning messages. It is advisable that users read these messages to make sure that there model is set up as intended. A possible reason for this occuring is when parameter files are out of date with the code in which case a missing parameter error message will be relayed.
Please consult the Atlantis Updates for a lists major repository revisions and the updates to include in your input files. In the case that you do not have any of the libraries or packages of the previous point installed, this is the way to install them on your machine using the terminal.
If you have questions, visit Wiki-Packages-Linux. On your terminal navigate to your Atlantis model folder and then convert the files:. You can download all these versions here. Follow instructions to download NetCDF 4. For further information see the Atlantis-Wiki. Building in Visual Studio requires opening the appropriate visual studio solution in the root Atlantis SVN repository folder. The build process should show all projects succeeding with 0 failings.
Step 2: The executable file atlantismain. To locally compile the code, create a new folder or checkout directory for your source code e. Right click in this new folder and select the new menu option "SVN checkout" and enter the appropriate URL of repository:. You will then be asked to authenticate using your domain username and password provided after registering to be a user. Open the dos command prompt window, navigate to your model run directory that has the. We would not recommend using Mac if you have a choice.
It generally takes a couple of hours and as much as a day per machine to set up. Its not as simple as running on Windows or Linux and you will need to be comfortable installing libraries from source.
Atlantis needs the following libraries to be installed. Initially, to include all the source code you will need to build the code via command line rather than using other developer software e. This will hopefully build an executable called atlantisNew in the atlantismain folder.
