CEHO Carlos Ortiz

Data consulting · Marine biologist & data analyst

Numbers you can defend.

Data consulting with a field scientist’s eye. I turn messy environmental and operational data into clear, defensible answers for companies and NGOs across Portugal, Spain and Latin America.

§1 · Services

Four ways I can help

From the first sampling plan to the final figure, with the reasoning written down so you can defend it.

01

Statistical analysis

Experimental design, hypothesis testing and modelling, with clear reporting for decisions and for publications.

02

Environmental impact

Baseline and monitoring studies, impact assessment and biodiversity indicators that hold up to review.

03

Data management

Scattered spreadsheets and field records restructured into clean, well-designed databases, with documentation.

04

GIS

Mapping and spatial analysis, with a focus on coastal and marine environments.

§2 · Selected work

The problem, and how I approached it

A few representative projects. Client names are kept confidential.

Case 01

Coastal GIS

Problem
Coastal data spread across sources, with no shared spatial picture.
Approach
Spatial mapping and analysis of the coastal environment in one consistent GIS.

Case 02

Biodiversity data analysis

Problem
Raw survey data that could not yet answer the ecological question.
Approach
From raw survey records to robust, documented ecological indicators.

Case 03

Database restructuring

Problem
Inconsistent datasets that nobody could query with confidence.
Approach
Redesigned into a correct, queryable database with clear documentation.

Case 04

Sampling design consultancy

Problem
Fieldwork about to start without a plan that matched the question.
Approach
Advice on sampling methods so the data answers the question before anyone gets wet.

§3 · About

From the reef to the dataset

I’ve spent close to 20 years under water as a professional diver, and years analysing data from ecology labs and factories. The settings changed; the common thread never did: a love of data analysis.

§4 · Beyond work

Where the biology and the data meet at home

I’m setting up my first marine aquarium: water chemistry, logs and a lot of patience. After two decades of diving, it’s a small piece of the sea to look after. I document it on Instagram.
