Here are examples of some projects where TeamSurv's technology and expertise are being applied.
Great Barrier Reef
James Cook University in Cairns, Australia have started getting boats operating in the Great Barrier Reef area to log data using TeamSurv's data logger. The data is used for their high resolution map of the area, as well as being provided to both TeamSurv and GEBCO. After initial trials during 2018, they are now rolling the project out on a larger scale.
We carried out a project under the UK Department for Transport's T-TRIG initiative looking at how crowd sourced bathymetry could be applied to ports and harbours round the UK. This was done by questioning many port and harbour operators, from the largest commercial ports to seldom used jetties, as well as an examination of some of our port and harbour data. We concluded that it is applicable for medium sized ports downwards, particularly where there is a mobile seabed, and especially for the local authority run municipal ports, due to the draconian cuts to local authority budgets imposed by the government.
The BASE Platform project is an EU supported research project into satellite derived bathymetry, and its use in conjunction with crowd sourced bathymetry. There are several methods of measuring water depth by satellite, but they all benefit from having in-situ or ground truth measurements to optimise their calculations for a given location. One of our main tasks in this project is to provide this data for the trials areas of the project. We are also using this project to improve some of our algorithms and further automate our data processing, and to have better presentation of the data on our web site. As part of this, we have moved from using coastal tide prediction stations to a global tidal model, and we have also produced a global monthly speed of sound atlas for correcting depths.
The Seafront project is a major Horizon 2020 supported project researching potential new antifouling paint technologies, with 17 partners and running over 4 years. Some of the new technologies being developed by the marine biologists and paint scientists is really exciting, and al of the avenues being explored are less damaging to the environment than those in current use.
Our role is in providing environmental monitoring data for the test paint samples, whether on a test raft, or deployed in real life on a vessel, an offshore energy platform or a fish farm. To do this, we are providing three different approaches:
- On the static platforms we are providing a set of water quality sensors that automatically record data to a standard TeamSurv logger. These are periodically removed by the local staff, and the data uploaded to our servers for processing in an extension to the standard TeamSurv data processing system.
- For vessels, we use the standard TeamSurv data loggers, but to make installation easier and to provide extra data we also provide a box for mounting on deck with a GPS and a light sensor, so we know the levels of daylight the vessel experiences. The crew upload this data as standard to TeamSurv. The tracks give the scientists information on the amount of time spent in the marina or port, as well as vessel speeds, which affect fouling growth.
- In both of the above cases, we also use Earth Observation (i.e. satellite) data and the outputs of oceanographic models for additional parameters. These are automatically downloaded to our servers on a daily basis, then the required parameters are extracted corresponding to vessel tracks and the positions of static platforms, and formatted as required by the scientists
These data sets are distributed to the scientists with weekly updates.
European Space Agency EOCrowd
We carried out a feasibility study for the European Space Agency (ESA) on the use of Open Data, Crowd sourced data and Earth Observation data for bathymetric data, in conjunction with Telespazio VEGA UK who provided expertise on satellite derived bathymetry. This looked at the technical benefits and challenges in combining data from these three sources, combining TeamSurv's automated processing against Telespazio's manual approach, and the availability, quality and licencing aspects of marine data that is either partially or fully open. It also looked at the demand for bathymetric data, the business case for a combined data set, and an analysis of the crowd for gathering data.
IHO Crowd Sourced Bathymetry Workgroup
The IHO can be seen as the umbrella body for national Hydrographic Offices.Their mission is to create a global environment in which States provide adequate and timely hydrographic data, products and services and ensure their widest possible use.A principal aim is to ensure that all the world's seas, oceans and navigable waters are surveyed and charted.
They have recently begun to address the lack of bathymetric data, both in international waters and also in many coastal areas. Having seen the benefits of crowd sourced data from projects such as TeamSurv, they are now working on promoting the use of crowd sourced data to their member states, and have set up a Crowd Sourced Bathymetry Working Group. TeamSurv is a member of the Working Group, advising the IHO on best practice to be incorporated into their cookbook and standards, and are also providing sample data sets.
The European Marine Observation and Data Network (EMODnet) consists of more than 100 organisations assembling marine data, products and metadata to make these fragmented resources more available to public and private users relying on quality-assured, standardised and harmonised marine data which are interoperable and free of restrictions on use.
Bathymetry is one of their key data sets, accessible through their bathymetry data portal. We are providing crowd sourced data in areas where there are no recent surveys, such as the Channel Islands and the Balearics. This is initially being done through EMODnet's links with the BASE Platform project, though we intend to continue supplying data after BASE Platforms finishes.
GEBCO consists of an international group of experts who work on the development of a range of bathymetric data sets and data products, including gridded bathymetric data sets, a world map and Gazetteer of Undersea Feature Names.
One of GEBCO's biggest challenges is a lack of data, as nobody has a responsibility for hydrographic surveying in international waters. A mainstay has been their use of satellite derived bathymetry, supplemented with tracks from research vessels, but now they are realising the benefits that crowd sourced bathymetry can offer. We have been advising them on this, for example through being invited to participate in the Forum for Future Ocean Floor Mapping, held in Monaco in June 2016. Out of this event it was also agreed that TeamSurv will provide a data feed to GEBCO, so TeamSurv data can be incorporated in their bathymetry models.
