Welcome to AEON's Data Portal. The AEON network concentrates all observation assets in the Gulf of Maine and totals 5 observation nodes. Node locations are determined based on an in-depth analysis of current regional assets and collaborations, bathymetry and associated sound propagation models, location historical and predicted oceanographic features, and ecosystem relevance.
For some data, you may need to use Globus for access. If you do not have a Globus Account, you will need to use Globus ID to sign in as a guest to download this data. (What's this?). Other data will be accessed directly via Figshare.
What is considered "RAW" data. When data is collected by the various instruments used for measurements, the “raw” data that is obtained is considered “Level 0”. Level 0 data is unprocessed instrument-specific or instrument-proprietary binary machine language data that is often unreadable by humans, some software, and common analysis packages. To be useful for science and archiving, machine-data must be processed to what is considered “Level 1” raw data. That is, raw data that can be archived in non-proprietary, non-instrument specific (open) file formats that facilitate long-term data storage and curation. Data generated during this project will in general, be processed, if necessary, into ASCII, .csv, or .pdf format.
The cruise reports provided below include ancillary data collected during each cruise to adequately address the question of temporal and spatial data correlation for both the active and passive datasets. The reports also provide location and time of instrument deployments and recoveries. Please click on the links below to see reports. Timing of data harvests go by deployment cruises. E.g. instruments deployed in the first deployment are harvested during the second deployment cruise. Therefore if deployed Feb 2021 and harvested July 2021, the data sampling was 5 months. All data except for FSAS and CTD are collected by instruments attached to the JASCO ALTO lander seated on the ocean floor at selected sites of the AEON network.
- First Deployment: Feb 2021 Beast initial deployment Cruise
- Second Deployment: July 2021 Beast 6mos service Cruise [JASCO Dataset 1]
- Third Deployment: Jan 2022 Warren Jr. Cruise [JASCO dataset 2]
- Fourth Deployment: Feb 2023 Warren Jr. Cruise [JASCO dataset 3]
- Fifth Deployment: March & April 2024 R/V Connecticut Cruise [JASCO dataset 4]
- Sixth Deployment: April 2025 R/V Connecticut Cruise [JASCO dataset 5]
Deployment Files provide metadata that describes where and when instruments were deployed and recovered. Site location, AMAR type/model, and duty cycles/ hertz. This location and time data can be tied to the VEMCO fish tag loggers, AZFPs, WBATs, and CTO-DO datasets as these instrument are attached to the same ALTO Lander that holds the AMAR passive sensor.
