Coral Bleaching & Marine Asset Risk API using Vercel AI SDK and Streaming SST Anomalies

Record-breaking ocean temperatures during El Niño trigger widespread coral reef bleaching, causing catastrophic losses for coastal tourism, marine aquaculture, and natural wave barrier insurance policies across the tropics. Marine asset insurers require real-time streaming APIs to track ocean heat content and alert policyholders before mass bleaching occurs. In this challenge, you will implement a web-native API using Vercel's AI SDK in TypeScript. The system will stream real-time analysis of NOAA Coral Reef Watch sea surface temperature (SST) anomaly feeds directly to client dashboards. Your solution will execute tool calling for spatial SST indexing, calculate Degree Heating Weeks (DHW), and stream structured risk assessments with low latency.

Delivery guide

How work is evaluated

Evaluation

Evaluates the accuracy of Degree Heating Weeks (DHW) calculations and TypeScript stream response structure.

Datasets

Challenge datasets

Public datasets, plus the private datasets you have access to.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

zod_schema_validation

Streamed object complies strictly with Zod definition

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

dhw_accuracy

Accuracy of Degree Heating Weeks calculation • target: 0.99 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
